Which equation represents the line shown on the coordinate right below

9514 1404 393

  A

Step-by-step explanation:

The line has positive slope (rises to the right) and a y-intercept of -2. The only matching choice is A.

__

Each of the equations is in slope-intercept form:

  y = mx + b . . . . . where m is the slope and b is the y-intercept

So, you need to choose the one that has m > 0 and b = -2.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

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

x       y
