Which is the equation of a line that is perpendicular to 6x – 4y = 9? a. y=-2/3x-4 b. y=2/3x+4 c. y=-3/2x d. y=3/2x-2

6x – 4y = 9

4y = 6x - 9

y = 6/4 x - 9/4

y = 3/2 x - 9/4 this line has slope = 3/2

perpendicular line, slope is opposite and reciprocal so slope of this line = -2/3

A.y= - 2/3 x - 4 (only this line has slope = -2/3)

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
