Answer:
y = 9x -3
Step-by-step explanation:
The given line is in "slope-intercept form"
y = mx + b
where m is the slope and b is the y-intercept (where it crosses the y-axis).
In your given line, we have ...
m = 9, b = 4
__
A parallel line will have the same slope, so we know that the line you want has m = 9. You are told to make the line cross the y-axis at -3, so that makes b = -3. Putting these values into the slope-intercept form gives the desired equation:
y = 9x -3
_____
The attached graph is intended to show the lines are parallel and the equation given here meets the requirement for a crossing of the y-axis at -3. The vertical and horizontal scales are different in order to better show these things.
