Step-by-step explanation:
1. true
2. false
3.true
4.false
5. ( may be false)
6 .(may be false)
Steps
8x−7y=−5
Add 7y to both sides
8x−7y+7y=−5+7y
Simplify
8x=−5+7y
Divide both sides by 8
8x
8 =−

8 +
7y
8
Simplify
x=
−5+7y
8
Step-by-step explanation:
-8 ( - 5 + 13) + 2 : 1 x 2
-8 ( 8) + 2 : 2
-64 + 1
-63
The zeroes (where the line crosses the x-axis, these are also the solutions) and the vertex (the highest or lowest point)
