Answer:
y =
x - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 4x + 38 is in this form with slope m = - 4
The line ST is perpendicular to line RS ( angles in a square are 90° )
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 
y =
x + c ← is the partial equation
To find c substitute (2, - 4) into the partial equation
- 4 =
+ c ⇒ c = - 4 -
= - 
y =
x -
← equation of ST

Hello!
<u><em>Answer:</em></u>
<u><em>w=12</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
First, you add by 5 from both sides of an equation.

Then, you simplify.

Next, you multiply by 3 from both sides of an equation.

And finally, simplify and solve. You can also multiply by the numbers from left too right.

Final answer: → 
Hope this helps!
Thanks!
