Question

Find the slope of the line that contains the points named.
E(0, 0), F(a, b)

Answer 1

slope = b/a

hope it helps

Answer 2

Slope is the velocity and is equal to (y2-y1)/(x2-x1), and is constant for a linear equation, (linear equation means that there is a constant velocity or rate of change.)  In this case:

(b-0)/(a-0)

b/a
