Answer:
<h2>b. 3 - 2x</h2>
Step-by-step explanation:

Hi!
Let's just take this part by part.
The sum of seven is the first part written. You can deduce from that, that it's 7 + something.
The next part is the quotient of a number x and 8. A quotient is the result of something being divided, so we can figure out that it's x / 8.
Putting it all together, you get the expression as 7 + x / 8.
Hope this helped!
Answer:
y = -4x - 1
Step-by-step explanation:
x - 4y = 24
-4y = -x + 24
y = 1/4x - 6
m⊥ = -4
y = -4x + b
7 = -4 ( -2 ) + b
7 = 8 + b
b = -1
y = -4x - 1
