Question

What is the solution to the system of equations?

y=-5x + 30
x= 10
o F-20, 10)
O (10.-20
O (10.4)
O (4.10)

Answer 1

B) (10, -20)

Explanation:

Plug in the values to y = -5x + 30 to see if they match:

we already know that x = 10 so are equation will always be:

y = -5(10) + 30 = -50 + 30 = -20

our new equation is y = -20

so your answer is B) (10, -20)

because the X-value has to be 10 and Y-value is equal to -20
