Question

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).

Answer 1

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
