Find the slope of each line. me 6-7 .

To find the slope, use this following formula
m = (y₂ - y₁) / (x₂ - x₁)

NUMBER 6
Given:
(x₁,y₁) = (0,-3)
(x₂,y₂) = (1,-1)

Solution:
plug the numbers into the formula
m = (y₂ - y₁) / (x₂ - x₁)
m = (-1 - (-3)) / (1 - 0)
m = (-1 + 3) / 1
m = 2/1
m = 2
The slope of the first line is 2

NUMBER 7
Given:
(x₁,y₁) = (0,5)
(x₂,y₂) = (1,3)

Solution:
plug the numbers into the formula
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - 5)/(1 - 0)
m = -2/1
m = -2
The slope of the second line is -2
