Question

What is the function rule for the line?

Answer 1

Answer:

A

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

with (x₁, y₁ ) = (- 3, 0 ) and (x₂, y₂ ) = (0, - 2 ) ← 2 points on the line

m = $\frac{-2-0}{0-(-3)}$ = $\frac{-2}{0+3}$ = - $\frac{2}{3}$

The line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

f(x) = - $\frac{2}{3}$ x - 2 ← function rule
