What is the slope of a line perpendicular to the line whose equation is 9x+6y=18
Luba_88 [7]

answer:

slope: -2/3

step-by-step explanation:

y=mx+b

m represents the slope, and b the y-intercept.

rearrange: 9x= -6y+18

---> -6y= -9x-18

divide all terms by -6.

-6y/-6= -9/-6x-18/-6

y= 3/2x+3 (slope/intercept form)

m= 3/2

---> 1/3/2= -2/3
