0, 3, -2, 8. You go up 8 rungs and you were halfway there so 16.
no you are actually doing really good keep it up
The first thing to do with these problems is to convert them into y=mx+b form; this will literally show you the answer to slope and y intercept since m=slope and b=y intercept.
To convert, isolate the y and the rest should fall into place. Subtract 2x from 4y and the other side of the equation to get the equation 4y= -2x+9 (put the x first because of mx+b). Then Divide the 4 from y and do the same to the other side to get y= -1/2x+9/4. M= -1/2 so that is the slope. B=9/4 so that is the y intercept
Answer: $18.52
Step-by-step explanation: First you multiply the grocery store purchases by 3%, then you multiply the other purchases by 1.5%. Then you add together to get your total cash back
$326.79x.03=$9.80
$581.34x.015=$8.72
$9.80+$8.72=$18.52
