Answer:</h2>
This is a 2-step equation. We will solve it in 2 steps.

The solution for this equation is x =<em> </em>
.
Answer:
4x + y = 15 or y = -4x + 15
Step-by-step explanation:
7 = 2[-4] + b
-8
15 = b

If you want it in <em>Standard </em><em>Form</em>:
y = -4x + 15
+4x +4x
___________
4x + y = 15 >> Line in <em>Standard Form</em>

Answer:
120 degrees
Step-by-step explanation:
Attached is a screenshot.
y = 180 - 50 - 70 = 60.
x + y = 180, so x = 120
Remember to try to use parallel lines when you can
The second uses the same method, just the opposite side.
The answer is c.
Since a^2+b^2=c^2, b^2=c^2-a^2 thus,
16=4-b^2= srt. of 12
y=-2
Step-by-step explanation:
if line has zero slope (b) it means that b is undefined.
if x=0 y=-2 because line has no slope. so b=-2
y=-2
