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.

How do you graph the equation y-x 3?

To graph the equation y-x=3, first rearrange it in slope-intercept form by isolating y: y=x+3. This equation represents a line with a slope of 1 and y-intercept of 3. You can plot the y-intercept at (0,3) then use the slope to find another point and draw a straight line connecting the two points.

How do you graph a linear equation with no slope or y-intercept such as y equals 5?

You would draw a straight horizontal line through the 5 on the y axis.


Can a linear equation be graphed with only the slope and intercept when it is in standard form?

That's all you need to know in order to draw the graph. Note that it doesn't matter what form the equation is written in. The form of presentation doesn't change the slope or intercept.


How do you plot linear equations by looking at a problem ex y8x 16?

The example, y = 8x + 16, is in slope-intercept form, the easiest to graph. First, you plot the point (0,16) because 16 is the plain number being added, the y intercept. Going from that point, you draw a line with slope 8. This means that, from the intercept, you draw a line that goes right 1 box, and up 8 boxes. Once you figure out what it looks like, you can continue the line without counting. This is a steep line.

How do you graph a line if given the equation in slope-intercept form?

Slope intercept form is y = mx + b, where m is the slope and b is the y intercept. To graph this, look at b. The number there is the y intercept. Look on the y axis on the graph and find the place where that number occurs. Plot that point, which will be (0, b). Then look at the m term. This is the slope. Imagine this number as a fraction. If it is a whole number, imagine it as the whole number divided by one. The fraction is the slope. The numerator is how far you move up or down, and the denomontator is how far you move left and right on the graph. Find the second point this way, then you can draw your line. Hope this helps!


What does it mean if the y intercept of x equals 2?

This would be a more meaningful statement if it said that the y intercept of the equation equals 2, which would mean that when you draw the equation on a graph, the line intersects the y axis at 2, or in other words, when x = 0, y = 2. However, as stated, x = 2 has no y intercept. If you graph it, that is just a verticle line located at 2 on the x axis.


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
