Question

PLEASE HELP FAST!!! Estimate the line of best fit using two points on the line.

Answer 1

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Calculate m using the slope formula

m = $\frac{y_{2}=xy_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (8, 5)

m = $\frac{5-8}{8-2}$ = $\frac{-3}{6}$ = - $\frac{1}{2}$

The line crosses the y- axis at (0, 9) ⇒ c = 9

y = - $\frac{1}{2}$ x + 9 → D

Answer 2

Answer:

D) y= -1/2x+9

Step-by-step explanation:

if u substitute y with 8 u will get 2

if u substitute y with 5 u will get 8
