Chapter 4 Test Review Algebra

Tell whether a correlation is likely in the situation. The amount of gas in a car's tank and the number of miles driven.

Negative

Determine if the given lines are parallel, perpendicular, or neither. 2x-3y=15 4x-5y=9

Neither

Tell whether a correlation is likely in the situation. The height of a person and the length of the person's toenails.

No correlation

Determine if the given lines are parallel, perpendicular, or neither. y=5 2y-3=15

Parallel

Determine if the given lines are parallel, perpendicular, or neither. 2-x=4y 2y+10=8x

Perpendicular

Determine if the given lines are parallel, perpendicular, or neither. y+x=1/2x+1 2x-y=3

Perpendicular
