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.

Hope This Helps You!

Good Luck (:

Have A Great Day ^-^

Answer:

(1,11) and (-1,-5) are both solutions

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
