Answer:
y=3x+1
Step-by-step explanation:
Your equation should start off as y=mx+b. You must solve for m and b, although they already give you m and b. m is the slope, which here is 3 and your y is 1. Making your equation, y=3x+1.
Answer:
y = 1/2x + 2
Step-by-step explanation:
y = mx+b, where m is the slope, b is y-int, and y and x are variables.
Step 1: find the y-int: 2. Using this you can out rule C and D.
Step 2: find the RISE/RUN: 1/2. This is your slope.
Step 3: fill in your equation.

The correct answer is A) $75.85.
A discount of 20% means that the cost is 80% of the original. 80%=80/100=0.8
0.8(129) = 103.20
A discount of 30% means that the cost is 70% of the amount before discount. 70%=70/100=0.7
0.7(103.20) = 72.24
A sales tax of 5% means that it is 105% of the amount pre-tax. 105%=105/100=1.05
1.05(72.24) ≈ 75.85
