Answer:
Step-by-step explanation: 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.
Answer: y=mx+b, m=(y2-y1)/(x2-x1), b=y-intercept, value of y when x=0
m=(-8-10)/(-2-1)
m=-18/-3
m=6
y=6x+b, using (1, 10) we can solve for b
10=6(1)+b
10=6+b
4=b so the line is:
y=6x+4
