Answer:

No

Step-by-step explanation:

To determine if the point (- 3, 5) is a solution to both equations.

Substitute the x and y values into the left side of both equations and if equal to the right sides then the point is a solution.

x - 3y = - 3 - 3(5) = - 3 - 15 = - 18 ← True

- 2x + y = - 2(- 3) + 5 =  6 + 5 = 11 ← False

Thus (- 3, 5) is not a solution to the system of equations.

Citrus2011 [14]

Answer:

y=x+6

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-6)/(2-0)

m=2/2

m=1

y-y1=m(x-x1)

y-6=x-0

y-6=x
