PLS HELP
Use elimination to solve each system of equations.
6x + 5y = 4
6x - 7y = -20

  Point Form:

                        ( − 1 ,2 )

Equation Form:

x = − 1 , y = 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
