Give the equation of the line parallel to 3x-4y=8 and passing through (12,1)?

Question

A. y=(3/4)x -8

B. y--(3/4)x + 17

C. y= (3/4)x - 15

2nd question:

give the equation of the line perpendicular to 2x+3y=7 and passing through (6,4)

A. y= (3/2)x - 5

B. y= -(3/2)x + 13

C. y= -(2/3)x - 15

Answer 1

1. Parallel means same slope

Slope is 3/4

When you enter 12 in as X for A, Y = 1 so Letter A is correct

2. Perpendicular has inverse slope with opposite sign

Slope is -2/3 so a perpendicular line is 3/2 slope

A is correct
