Answer:
Rick is correct
Step-by-step explanation:
Pretty sure the answer is D:
Because the equation is in the format y=mx+c (c being the y intercept), we know that the y intercept (or where the line will cross the y axis) will be -9.
B also says -9 but we have to be careful because it states that the x axis is -9 rather than the y axis.
Hope that helped you understand.
Part A:
Price before tax: $49.99
Discount: 50% of $49.99 = 50% * $49.99 = 0.50 * $49.99 = $25.00
Discounted price: $49.99 - $25.00 = $24.99
Tax on discounted price: 8% of $24.99 = 8% * $24.99 = 0.08 * $24.99 = $2.00
Part B:
Total price: $24.99 + $2.00 = $26.99
Answer:
m=-2 c=3
Step-by-step explanation:
y=mx+c
rearrange
-mx-c+y=0
original
y=2x-3
