Answer:
y = 5x + 3
Step-by-step explanation:
Slope-intercept form is y=mx+b (where m is the slope and b is the y-intercept)
First find the slope with (13-8)/(2-1) = 5
Plug the slope and one of the coordinates into the equation to find the y-intercept now:
13 = 5 * 2 + b
13 = 10 + b
b = 3 (y-intercept is 3)
Now, write final equation: y = 5x + 3
Answer:
$15
Step-by-step explanation:
The original price of the mirror is unknown, so let's call it x.
The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.
B is the answer because you want to do the opposite
