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
