Answer:
A
Step-by-step explanation:
You can make a proportion of 8/20 to 42/x and then simply cross multiply from there to solve for y
Given:
The point, (4, -3)
The line,

To find an equation in slope-intercept form for the line that passes through (4,-3) and is parallel to the given line:
The slope of the line is,

Since the given line is parallel to the new line, so the slope will be same for the both.
Using the point-slope formula,

Substitute the point and slope we get,

Hence, the equation in slope-intercept form for the line is,
I am pretty sure it is linear decrease,
