If you would like to solve the equation -5x - 25 = 78, you should do this using the following steps:
<span>-5x - 25 = 78
</span>-5x - 25 + 25 = 78 + 25
-5x + 0 = 103
-5x = 103 /(-5)
x = 103 / (-5)
x = - 103/5 = - 20.6
The error was already made at step 1.
Thats it option (C). Hope it helps!!

Answer:
y=-5x+7
Step-by-step explanation:
Prallel lines have the same slope
so the slope of the unknown line is -5
and passes through(1,2)
y-2=-5(x-1)
slope-intercept form:y=-5x+7
