➷ Substitute the values in:
1st option:
y = 8(1) + 3
y = 11
2nd option:
y = 8(-1) + 3
y = -5
The correct answer would be both.

Answer:
(1,11) and (-1,-5) are both solutions
Step-by-step explanation:
To determine if it is a solution, we substitute x into the equation and see if it gives us y
y = 8x+3
Let x =1
y = 8(1) +3
y = 8+3
y= 11
(1,11) is a solution
Let x = -1
y = 8(-1) +3
y = -8+3
y = -5
(-1,-5) is a solution
