Answer:

c)
Step-by-step explanation:
the x rate of change is +2 and the y rate of change if -1. slope is always y over x, therefore, do exactly that. put y (-1) over x (2). thus gett in your answer of the slope.
Answer:
AE-3*x+7=0 and CE=5*x-7
Step-by-step explanation:
-3*x and -7 move these terms to the left it becomes AE-3*x-7=0 do the same step that you did with the first one.
Answer:
y= 2.08
Step-by-step explanation:
4.58 - 2.5
4.58
- 2.50
-----------
2.08
First, You Do 10 and 12 in the parentheses, then subtract 8 and multiply 7. Then This Equals 146. Hope this helps :)
Answer:
C
Step-by-step explanation:
Perpendicular lines have the exact opposite slope of the other equation.
So the slope will be x or 1x. Plug in
-8 = 1(4) + b (b represents y-intercept) like y=mx+b
-8 = 4 + b (subtract 4 on both sides)
-12 = b
The equation is y = x - 12
C
solve
y + 8 = x - 4 (subtract 8 on both sides)
y = x - 12
