Answer:

y = 1/3x + 6

Step-by-step explanation:

Rearrange equation to get y by itself.

3x + y = -1

y = -3x - 1

Perpendicular = opposite reciprocal. This means that the slope = 1/3

Convert to point-slope form: y - y1 = m (x - x1)

y - 5 = 1/3 (x - (-3))

y - 5 = 1/3 (x + 3)

y - 5 = 1/3x + 1

y = 1/3x + 6

if ZA and ZB are supplementary angles. if mZA = (3x-23) and mZB= (2x-12) then find the measure of ZB​
Brilliant_brown [7]

Answer:

mZB= 74

Step-by-step explanation:

ZB+ZA=180

3X-23+2X-12=180

5X-35=180

5X=180+35

5X=215  (then divide both sides by 5 to x be left alone.)

X=43....so ZB=2(43)-12

                     =86-12=74
