To find the equations of this solution substitute x by 0.5 in each equation if the answer equal 3, then this solution is for the equation
Let us do that
A) y = 2x + 2
Put x = 0.5
y = 2(0.5) + 2
y = 1 + 2
y = 3 as the value of y in the ordered pair
(0.5, 3) is the solution of y = 2x + 2
The answer is A
