Ive done the math and its 7.75
Answer:
y = 2/5x - 2
Step-by-step explanation:
y inter = -2
slope is rise / run = 2/5
C is correct.
1. You do 12.99 times 3
2. $0.69 times 2
3. Add $2.99 to the two prices above
4. Add the $2.52 tax to the prices
And you should get around $45 and some change
So you’ll have to isolate the y by dividing the other side of the equation by 3
3y=-x-3
y=-1/3x-1
-1 will be your y intercept and the slope will be -1/3
you’ll start your line by plotting (0,-1)
then from that point you’ll count down one, right 3
or up one, left 3
hope this helps (:
The answer is B. Just multiply all of them then divide
