Answer:
y = 3x - 9
Step-by-step explanation:
We first need to find the slope (m)
m = =
=
= 3
y = mx + b
y = 3x + b
(4, 3)
y = 3x + b
3 = 3(4) + b
3 = 12 + b
-12 -12
-9 = b
(1, –6)
y = 3x + b
-6 = 3(1) + b
-6 = 3 + b
-3 -3
-9 = b
y = 3x - 9
To check: (1, –6)
y = 3x - 9
-6 = 3(1) - 9
-6 = 3 - 9
-6 = -6
Hope this helps!
Answer:
Mattison paid 54 after the discounts for 2 jeans.
Step-by-step explanation:
Original price of the jeans = 35.99
Discount on the jeans = 25%
So, discounted amount on each jeans =
So, the actual amount paid for 1 jeans = Actual Price - Discounted amount
= 35.99 - 8.99 = 27
So, the price paid for 2 jeans = 27 x 2 = 54
Hence, Mattison paid 54 after the discounts for 2 jeans.
