General formula to determine the equation of the line
y - y₁ = m(x - x₁)
(x₁,y₁) is one of the points which lies n the line
m represents the slope
Find the slope
Given:
(x₁,y₁) = (6,-6)
(x₂,y₂) = (8,8)
We could find the slope by using this formula
m =
Plug in the numbers
m =
m =
m =
m = 7
The slope is 7
Determine the line equation
Plug one of the points (you could choose any of points given from the question) and the slope to the formula of line equation
y - y₁ = m(x - x₁)
y - (-6) = 7(x - 6)
y + 6 = 7x - 42
y = 7x - 42 - 6
y = 7x - 48
<em>This is the equation of the line</em>
