Using the slope formula, find the slope of the line through the points (0,0) and (5,15) . Use pencil and paper. Explain how you can use mental math to find the slope of the line.

Slope = 3

Step-by-step explanation:

The formula for calculating the slope is expressed as:

m = y2-y1/x2-x1

From the coordinate, x1 = 0 y1 =0 x2 = 5, y2 =15

m = 15-0/5-0

m = 15/5

m = 3

Hence the slope is 3

the equivalent expression are always the hardest ones but you look at the gcf also
