When graphing using slope-intercept form (y = mx + b), you first plot the y-intercept, which is the point where the line crosses the y-axis (at the point (0, b)). After plotting the y-intercept, you use the slope (m) to determine the rise over run from that point to find another point on the line. Finally, you can draw the line through these two points.

When you graph a line using slope intercept form do you start by graphing m or b first?

Start with b. To do this, plot the point (0, b). "Begin with B and Move with M!"


What is first step in graphing using slope intercept form of an equation?

Plot the y-axis, which is the b in the y=mx+b in the slope intercept equation. Then, you put your slope and plot the line.


Graphing linear equation using the slope and y-intercept of the line?

The y-intercept, together with the slope of the line, can also be used in graphing linear equations. The slope and y-intercept of a line can be obtained easily by inspection if the equeation of the line is of the form y=mx+b where m is the slope and b is the y-intercept.

How do you graph a line in slope intercept for?

1) You write the equation in slope-intercept form, if it isn't in that form already. 2) An easy way to graph it is to start with the y-intercept. For example, if the intercept is +5, you graph the point (0, 5). Then you add an additional point, according to the slope. For example, if the slope is 1/2, you go 2 units to the right, and one up, and graph a point there.

How do you plot 3x minus 4y equals 4?

Put it into slope intercept form and then proceed to use your favorite method of graphing. slope-intercept: y = -3x + 1


Why is it easier to graph x y 10 without rewriting it in slope-intercept form and then graphing?

Graphing the equation (x + y = 10) directly is easier because it allows you to quickly identify intercepts. You can find the x-intercept by setting (y = 0) (which gives (x = 10)) and the y-intercept by setting (x = 0) (which gives (y = 10)). Plotting these two points and drawing a line through them is straightforward, making the process quicker than converting to slope-intercept form.
