Decide if the graphs of each pair will be parallel, perpendicular or neither. a. y = -2x + 5 and y = 1/2x - 7 b. y = 3x + 9 and 3y - x = 6 c. 4y - x = 8 and y = 1/4x - 3 part b // find the equation of the line that is: a. parallel to y = 3x - 5 and passes through (-2, 1). b. perpendicular to y = -2/5x + 7 and passes through (4, 6).

so parallel is just numbers with the same slope but different x value

and perdicular is the One with different signs and oppisite reciprocals

a) perpendicular because -2 is the oppisite sign and reciprocal of 1/2

b)neither

c) niether

and B)

a) 3x-2

b)y=5/2 +4

i think

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

0       8

1       7.6

2       7.2

3       6.8
