Question

I’m thinking the answer is A :) A. Y=2x+4 B. Y=4x+2 C. Y=2x-4 D. Y=4x-2

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 ) = (- 2, 0) and (x₂, y₂ ) = (0, 4) ← 2 points on the line

m = $\frac{4-0}{0-(-2)}$ = $\frac{4}{0+2}$ = $\frac{4}{2}$ = 2

The line crosses the y- axis at (0, 4 ) ⇒ c = 4

y = 2x + 4 → A
