Step-by-step explanation:
To find the slope of a line which is perpendicular to another line, you need to find the opposite reciprocal of the first line's slope.
To find the opposite, flip the slope's sign. Your original slope is , so your opposite slope is positive
.
To find the reciprocal, flip the fraction. This changes your slope from to
, which may be written as just 7.
Therefore, your slope is 7.
To find your b term (your y-intercept) given that your x-intercept is -7, you can make use of point-slope form.
<em>(m=slope)</em>
If your x-intercept is -7, then the point at which your line intersects the x-axis is (-7, 0).

Step-by-step explanation:
Hi there!
We are given the absolute value equation:
5-8|-2x|=-80
We want to solve it for x
First, let's make sure that ONLY the absolute value equation is on the left side
So subtract 5 from both sides
-8|-2x|=-85
Now divide both sides by -8
|-2x|=85/8
Now, for an absolute value equation, we can split it up into two parts, as |x| can be equal to both x and -x
In this case, |-2x| can equal to 85/8, but it can also equal -85/8
That's why for absolute value, there are always 2 cases
For the first case, if |-2x| is equal to 85/8:
Note: we open up the absolute value when we are solving a case, as it is one of the possiblities that can happen for the equation. So it would be true.
-2x=85/8
Divide both sides by -2
x=-85/16
In the second case, if -2x is equal to -85/8:
-2x=-85/8
Divide both sides by -2
x=85/16
So the answers are
Hope this helps!
