Question

Calculate the slope of the points (-2, -1) and (3, 4). Show all of your work.

Answer 1

`m = (y_(2) - y_(1))/(x_(2) - x_(1)) = (4 - (-1))/(3 - (-2)) = (4 + 1)/(3 + 2) = (5)/(5) = 1`

y - y₁ = m(x - x₁)
y - 4 = 1(x - 3)
y - 4 = 1(x) - 1(3)
y - 4 = x - 3
+ 4 + 4
y = x + 1

Answer 2

The slope is found using the formula;
=
`(change in y)/(change in x)`
=
`(4--1)/(3--2)`
=
`(5)/(5)`
