Step-by-step explanation:
Answer:
x=-1 y=2
Step-by-step explanation:
Use Elimination or Substitution (Elimination shown below)
6x+5y=4
6x-7y =-20 <- Multiply by -1
-6x+7y=20
12y = 24
y=2
Plug back into either of the equations and solve for x.
6x + 10= 4
6x = -6
x = -1
Double check work:
-6+10 = 4

Answer:
y = -1/2x + 2
Step-by-step explanation:
A perpendicular line will have a opposite reciprocal slope.
Since the line's slope is 2, the perpendicular line will have a slope of -1/2
Plug in the slope and given point into y = mx + b, and solve for b
y = mx + b
3 = -1/2(-2) + b
3 = 1 + b
2 = b
Plug in the slope and b into y = mx + b
y = -1/2x + 2
So, the equation is y = -1/2x + 2
