Answer:
C. (1, 7)
Step-by-step explanation:
Why? Because if you substitute the x-coordinate which is 1 to the x and y-coordinate which is 7 to the y, it will satisfy the equation.
y = 2x + 5
7 = 2(1) + 5
7 = 2 + 5
7 = 7 ✓
And if you will check the others, it will not satisfy the equation.
(-4, -8)
y = 2x + 5
-8 = 2(-4) + 5
-8 = -8 + 5
-8 = -3 ×
(-4, 3)
y = 2x + 5
3 = 2(-4) + 5
3 = -8 + 5
3 = -3 ×
(2, 7)
y = 2x + 5
7 = 2(2) + 5
7 = 4 + 5
7 = 9 ×
