Answer:
see explanation
Step-by-step explanation:
Choose any value for x, substitute into the equation and solve for y, that is
x = - 1
2(- 1) + y = 8
- 2 + y = 8 ( add 2 to both sides )
y = 10
---------
x = 0
2(0) + y = 8
0 + y = 8
y = 8
----------------
x = 1
2(1) + y = 8
2 + y = 8 ( subtract 2 from both sides )
y = 6
---------------
x = 3
2(3) + y = 8
6 + y = 8 ( subtract 6 from both sides )
y = 2
----------------
4 possible solutions are (- 1, 10 ), (0, 8 ), (1, 6 ) and (3, 2 )
It would be -(-31) because a negative and negative is a positive
Push-Ups 10 30 40 60

Time (min) 1 3 4 6
If Mason can do 10 push-ups in a minute then all you have to do is multiply 10 by the time. For example: 10(push-ups) x 3(min) = 30</span>
