Answer:
y = 2x - 2
Step-by-step explanation:
y2 - y1 / x2 - x1
6 - 2 / 4 - 2
4 / 2
=2
y = 2x + b
2 = 2(2) + b
2 = 4 + b
-2 = b
Answer:
<h2>-9</h2>
Step-by-step explanation:
This would be -27/3 = -9
4b + 6 = 2 - b + 4
Combine like terms on the right side:
4b + 6 = -b + 6
Subtract 6 from both sides:
4b = -b
Add 1b to both sides:
5b = 0
Divide both sides by 5:
B = 0
Answer:
x = 5, <DEG = 112, <GEF = 68, <DEF = 180
Step-by-step explanation:
<DEG + <GEF = 180
23x - 3 + 12x + 8 = 180
35x + 5 = 180
Subtract 5 from both sides
35x = 175
Divide each side by 35
x = 5
Plug x = 5 into <DEG
23x - 3
23(5) - 3
<DEG = 112
Plug x = 5 into <GEF
12x + 8
12(5) + 8
<GEF = 68
<DEF is a straight angle so it automatically is 180
