Y = -7 + 2x
slope =
y-intercept =

The slope is 2 and the y intercept is -7

Step-by-step explanation:

y = -7 + 2x

Rearranging

y =  2x -7

This is in the form y = mx+b where m is the slope and b is the y intercept

m = 2 and b = -7

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
