Answer:
A = - 12 , B = - 8 , C = - 4
Explanation:
substitute the value of x above the letters into the equation and solve for y
x = - 2
2(- 2) - y = 8
- 4 - y = 8 ( add 4 to both sides )
- y = 12 ( multiply both sides by - 1 )
y = - 12 ← value of A
x = 0
2(0) - y = 8
0 - y = 8- y = 8 ( multiply both sides by - 1 )
y = - 8 ← value of B
x = 2
2(2) - y = 8
4 - y = 8 ( subtract 4 from both sides )
- y = 4 ( multiply both sides by - 1 )
y = - 4 ← value of C
