The answer has to resemble y=Mx+b so to find your y intercept plug in your coordinates into that equation so put your slope in for m and your x intercept in for x and the y intercept in for y so -4= -3(-1)+b now get b alone -1=b so your equation would be y=-3x-1

both angles
Answer:
y = -2
Step-by-step explanation:
10 -5y = 20 { subtract 10 from both sides}
-5y = 20 - 10
-5y = 10 {Divide both sides by (-5) }
y = 10/-5
y = -2
