How do you get the y intercept without having to draw a graph?
You can put the equation into slope-intercept form and the answer is right there, or you can put it in standard form and make the x coefficient and x "disappear" and solve the equation by dividing the number with y by the number on the other side of the equation.

Does y equals 5 have a slope?
Yes.Technically all equations in Slope Intercept Form have slopes and y intercepts.Slope Intercept Form is y = mx + b. (Where mx is the slope of the line and b is the y intercept.)In your particular equation you can infer that 5 is the y intercept because you don't have your x variable there.The slope in this case is 0, meaning your line is going to be horizontal across point (0, 5). (The y intercept)Another way to write this equation which will make finding the slope much easier is y = 0x + 5. Because the equation says 0x, there is no need to put it.It's like the difference between just saying x or saying 1x.
Does a change in the y intercept make the line more or less steep?
Neither. Changing the y-intercept will simply move the line up or down the y-axis.The "steepness" is all a matter of the slope.Now that we said that, we can think of a situation where changing the y-interceptwould change the slope of the line:That would be where you were given the y-intercept and one other point, and youhave to find the slope, or find the equation, or draw the line.If somebody sneaks in and changes the y-intercept, but leaves the other point rightwhere it is, then the slope of the line changes, (and so does the equation).
How do you graph the equation y equals x minus 1?
Well that is in y intercept slope form so what you do is you make an x/y table. putting -2,-1,0,1,2 on the x axis and then multiply each of them by 1 and -1. then they form ordered pairs and you graph them! hope that helped!! An easier way to graph it would be to do this. The (x) is the slope and the (minus 1)(-1) is the y-intercept. So first you would go down one on the graph you made, (on the y-axis), and put a dot on the point (0,-1). Then by graphing the (x), you would go up 1, then right 1, up 1, right 1, and so on, until you reach the edge of the graph, and then trace a straight line through the points. Then to properly detail it, put an arrow on each end of the line. and write the equation (such as the one you graphed), above the lined equation. I Think you should get a 100% on that, your welcome
How do you graph d equals 338t plus 299?
this is a linear equation. make the y-intercept at 299. and the slope of 338rise and 1run. this is an extremely steep slope.
How do you graph an algebraic expression?
To graph an algebraic expression, you must first make it into an equation that takes slope intercept form. Ex:The y value=slope(m) times the x value plus the y-intercept(b). Then you draw a graph and set your pencil on the corresponding y-intercept. Remember, slope is rise over run so count how many spaces up or down and then count the spaces to the right or left.Draw a line that goes through these points and then you have your line! ~Hope It Helps
How do you make and equation on a line in a graph?
The equation for the slope of a linear equation is Y=Mx+b, where m is the slope of the line, (Rise over run) and where B is the Y-intercept. (Where it crosses the Y axis)
What are 3 different methods that can graph a linear equation?
You could put the equation in slope-intercept form or in parent linear function or even make a table of values.
How do you graph a line on a graph?
well you use a formula ..... the one that i use most is y=mx+b this formula is slope-intercept formula the slope of the line is m, and the intercept is the b(the y intercept). Say the slope(m) is 3/2 the starting from the y intercept (in this case let it be 2, which is the coordinate [0,2]) you would go to the right 2 units and up 3 units(3/2=rise/run) to get another point. With that point(which in this case would be [2,5]) you can make a straight line through the two points to get your line on the graph. you can make as many points as you want, just keep using the slope(in this case 3/2). Another way, with graph paper: if you are dealing with a straight line, then pick two values of x, and solve for the respective y values. Plot these two points on the graph paper, then using a straight edge, connect the dots, and extend beyond each point.

Write the equation in slope intercept form and sketch the graph and please show steps?
Slope-Intercept form is the form y=mx+b. Sketching the graph involves plotting the line on the coordinate plane. The easiest way to do that is to create two different points from the equation, plot them on the graph and trace a line through them with a ruler. Showing your steps means showing how you got the equation. Make sure that any math you do in your head you put on the paper. Other than that I don't know how to answer this. Was there supposed to be an actual equation with it?
How do you graph the line represented by the equation x -2?
first make it fit into the standard formula.(y=mx+b) y=1/1x-2 1/1 is the slope and -2 is the y intercept.

Describe a situation in which point-slope form would be more useful than slope-intercept form?
You use point-slope form to find the equation of a line if you only have a point and a slope or if you are just given two point. Usually you will convert point-slope form to slope-intercept form to make it easier to use.
How do you find x with two points and a slope?
The slope is usually derived from the equation y = mx + b where m is the slope and b is the y-intercept. Slope: m = (y2 - y1)/(x2 - x1) As for finding intercepts, for finding the y intercept, look for the b in the equation or make x = 0, for x-intercepts, make y = 0.
