Answer:
y=-2x-4
Explanation:
So remember this y=mx+b
The M is the slope and the B is our y-intercept
So according to the picture it gave you the slope and the Y-intercept
The slope was -2 and the y-intercept was -4
So y=mx+b so subtitute the m to -2 and the b to -4
The equation should be y=-2x-4
I really hope this make sense
