Answer:
y + 2 = (3/2) (x+3) (point slope form)
Explanation:
(see attached for reference)
Given
(x₁, y₁) = (-3,-2)
(x₂, y₂) = (1,4)
Since we are given 2 points, it would be easiest to express the equation of the line in point-slope form (see attached)
(y - y₁) = m (x - x₁)
we already have the values for x₁ and y₁, hence we only need to find the slope m (see 2nd attached graphic)
m = (y₂-y₁) / (x₂ - x₁)
= [4 - (-2) ] / [1 - (-3)]
= (4+2) / (1+3)
= 6/4
= 3/2
substituting the value for m and the values for x₁ and y₁:
(y - y₁) = m (x - x₁)
[y - (-2)] = (3/2) [x - (-3)]
y + 2 = (3/2) (x+3)
