Answer:
Step-by-step explanation:
a.) Graph the points onto the graph according to the table i created.
b.) 2x + y = -3
+2x +2x
y = 2x - 3
She is incorrect. The correct linear equation is y = -2x - 3
1. x=1
5x=4+x
4x=4
x=1
2. x=3/4 or 0.75
2/3x=1/2
2x=1 1/2
x=3/4
3. x=1
3x-2x+4=15/3
x+4=15/3
x=1
4. x=5
4x+7=2x+17
2x+7=17
2x=10
x=5
5. x=20
.5x=10
x=20
