Question 13

Answer 1

The correct answer is y = 4x - 12

Answer 2

Answer:

C

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 ) = (4, 4) and (x₂, y₂ ) = (0, - 12)

m = $\frac{-12-4}{0=4}$ = $\frac{-16}{-4}$ = 4

The line crosses the y- axis at (0, - 12 ) ⇒ c = - 12

y = 4x - 12 ← equation of line → C
