Answer:
-4
Step-by-step explanation:
The slope is the number (& sign) attached to the variable x.
Remember to follow the slope-intercept form: y = mx + b.
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. ∴
First, add 4x to both sides:
-4x (+4x) - y = -5 (+4x)
-y = 4x - 5
Next, divide -1 from both sides (to make the variably y positive):
(-y)/-1 = (4x - 5)/-1
y = (4x - 5)/-1
y = -4x + 5
Slope intercept form: y = mx + b, in which m = slope, ∴ -4 is your answer.

Answer:
a) $8.80
b) 40%
Step-by-step explanation:
<u>Part (a)</u>
Given:
- Original price = $22
- Discounted price = $13.20
Original price - discounted price
= $22 - $13.20
= $8.80
<u>Part (b)</u>
percentage = (amount discounted ÷ original price) x 100
= (8.80 ÷ 22) x 100
= 40%
