Leo knows that the slope of a line is 4 and the line passes through the point (-7, 18). Without doing any calculations, can Leo easily write an equation for the line in slope-intercept form? Why or why not? Record your thoughts in the bubble at the right.
Write an equation in point-slope form given a point on the line and the slope of the line.
1. (8, 3), m = 4
2. (-6, 12), m = -2
3. (-2, -11), m = 5/2
