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

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