Question

Help please in y= mx + b form

Answer 1

Answer:

y = - $\frac{1}{2}$ x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, - 6) and (x₂, y₂ ) = (2, - 9) ← 2 points on the line

m = $\frac{-9+6}{2+4}$ = $\frac{-3}{6}$ = - $\frac{1}{2}$

Note the line crosses the y- axis at (0, - 8) ⇒ b = - 8

y = - $\frac{1}{2}$ x - 8 ← equation of line

Answer 2

Answer:

y= -2 x -8
