Question

Line AB contains points A(3,-2) and B(1,8). the slope of line AB is?

Answer 1

its -5

Explanation:

i took the test:)

Answer 2

The slope of a line is
`(y_2 - y_1)/(x_2 - x_1)`. We have the points (3, -2) and (1, 8). Let's substitute those into the formula.

`(8 - (-2))/(1-3)`
subtracting a negative is the same as adding, so that makes our equation

`(8+2)/(1-3)`

`(10)/(-2)`
slope = -5
