Answerrr is the equation of the line whose graph is shown?

a. y=-x

b. y=2x

c. y=x

d. y=2

A

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

To find m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (- 1, - 1) ← 2 points on the line

m = = = 1

y = x ← is the equation of the line → A
