Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
After using the slope formula your answer would be 5/0.1 but when simplifying your answer is 50
Equation is y^20 = ( )^2
Answer:
y to the power of 10.
