OpenStudy (anonymous):

slope intercept form is y = mx + b where m is slope and b is y-intercept. You can find the slope by counting the boxes between the two points. Slope = rise/run. How many boxes does the line move down between the points on the left and right?

im not sure

OpenStudy (anonymous):

alternatively you can use this formula for slope where you plug in the points \[y=\frac{ y_2-y_1 }{ x_2-x_1 }\]
