The second choice. Intersects means cuts the y axis. And if you go to -infinity (figuratively speaking! lol) x^3 dominates and goes to -infinity, way down, the other way for infinity

Answer:

y = - 2x - 1

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, 5) and (x₂, y₂ ) = (2, - 3)

m = $\frac{-3-5}{2+2}$ = $\frac{-8}{4}$ = - 2

The line crosses the y- axis at (0, - 1) ⇒ c = - 1

y = - 2x - 1 ← equation of line
