Question

The slope of the line through the points (0,-3) and (4,9) is

Answer 1

3

Explanation:

Subtract the y's -3-9= -12

then subtract the x's 0-4= -4

therefore -12/-4 = 3

Answer 2

The slope is 3.

Explanation:

Use the formula m = (y2-y1)/(x2-x1)

Then substitute the values into the formula

It should look like this: m = (9-(-3))/(4-0)

It will look like this: m = (9+3)/4

Next, it will be m = 12/4

So, m = 3
