Question

Which equation hasd a graph parallel to the graph of 9x+3y=-22

Answer 1

Answer:

3x + y = b

b - any real number

Step-by-step explanation:

Parallel lines have the same slope.

We have the equation of a line in the standard form Ax + By = C.

Convert to the slope-intercept form y = mx + b

m - slope

b - y-intercept

$9x+3y=-22$         subtract 9x from both sides

$3y=-9x-22$         divide both sides by 3

$y=-3x-\dfrac{22}{3}$

Therefore we have the slope m = -3.

Put it to the equation of a line:

$y=-3x+b$            add 3 to both sides

$3x+y=b$
