Answer: y = −2
Step-by-step explanation:
- 0 = −4x − 2
- x = −1/2
- To find the y-intercept, substitute in 0 for x and solve for y. Y = − 4 * 0 −2
- Which then gives you y = - 2

Answer:
Her friend got the better deal.
Step-by-step explanation:
For Jillians equation look at
$22.56/4 = $6.39 per CD
For her friends equation look at
$18.45/3 = $6.15 per CD
Jillian's friend got the better deal because she paid less per CD as shown in the equations above.
Y-2x=-3.5
x-2y=-14
then multiply the first term by 2
2y-4x=-7
x-2y=-14
then sum them
-3x=-21
x=-7
y=3.5
