Question

What is the slope of the line that contains the points (-1,2) and (3,3)

Answer 1

B

Explanation:

Hi there!

We are given the points (-1,2) and (3,3) and we need to find the slope.

The formula for slope calculated from two points is
`(y_(2)-y_(1) )/(x_(2)-x_(1))`, where (
`x_(1)`,
`y_(1)`) and (
`x_(2)`,
`y_(2)`) are points

since we have two points, we can substitute them into the formula, but let's label their values to avoid any confusion

`x_(1)`=-1

`y_(1)`=2

`x_(2)`=3

`y_(2)`=3

now substitute into the formula (m is the slope); remember: we have a negative number in this, so we'll be subtracting a negative.

m=
`(3-2)/(3--1)`

simplify

m=
`(3-2)/(3+1)`

m=
`(1)/(4)`

so B is your answer

Hope this helps! :)
