Please help! I will mark as brainliest IF answer is right. <3

y = 4x + 3

Step-by-step explanation:

Calculate the slope m of the given line using the slope formula

m =

with (x₁, y₁ ) = (- 4, 3) and (x₂, y₂ ) = (4, 1) ← 2 points on the line

m = = = = -

Given a line with slope m then the slope of a line perpendicular to it is

= - = - = 4

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

The line crosses the y- axis at (0, 3) ⇒ c = 3

y = 4x + 3 ← equation of perpendicular line

hopefully im right

a. the residual plot for model 1 has a random pattern and is a good fit for the data.
