What is the slope-intercept equation of the line below?

Kay [80]

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 = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (- 1, 1)

m = $\frac{1+1}{-1-0}$ = $\frac{2}{-1}$ = - 2

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

y = - 2x - 1 → C
