Question

What is the slope of the line that passes through the points (-10,8) and (-15,-7)

Answer 1

slope = m , m = rise / run rise = change in y run = change in x

Explanation:

to find change in y just subtract the second y from the first , like thus,

P1=(-10,8) = (X1,Y1)

P2=(-15,-7) = (X2,Y2)

-7-8=-15= change in Y

to find the change in X just subtract the second x from the first, like thus,

-15-(-10) = -15+10 = 5

m= -15/5

m=-3

it's a slope of negative 3... make sense?

Answer 2

3

Explanation:

Use the formula y2-y1/x2-x1

Plug in the values (-7-8)/(-15-(-10))

-15/-5
