(-5x+7y=11) - (-5x+3y=19) =
4y = -8. (divide both sides by 4)
y = -2
Substitute
-5x + 7(-2) =11
-5x - 14 =11
-5x = 25
x = -5
y = -2 and x = -5
Answer:
y = -x +3
Step-by-step explanation:
Think about the Y= mx + b
m = -1 so it's -x
b = 3, so it's +3
y intercept goes after the slope:
Y= Mx + B
Y = -x + 3
