Which equation has the graph parallel to the graph 9x + 3y =-22
y=3x-22****
y=-3x + 8
y=1/3x + 12
y = -1/3x-2

Please check my answer

nope.

9x+3y = -22 has slope -3

better review how to find the slope.

Write your equation in explicit form:

y = m x + n

where:

m is the slope of the line

n is the y intercept


9 x + 3 y = - 22 Subtract 9 x to both sides

9 x + 3 y - 9 x = - 22 - 9 x

3 y = - 9 x - 22 Divide both sides by 3

y = - 9 x / 3 - 22 / 3

y = - 3 x - 22 / 3

Parallel lines have the same slope m

In this case m = - 3

Line with slope m = - 3 is:

y = - 3 x + 8


So:

9 x + 3 y = - 22 and y = - 3 x + 8

are parallel lines
