Answer:
y=-4x-17
Explanation:
You want to find the equation for a line that has a slope of -4 and a y-intercept of -17.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
All you really have to do here is
replace m with -4, which is the slope you gave, and
replace b with -17, the y-intercept you gave,
in the equation y=mx+b.
The equation of the line that has a slope of -4 and a y-intercept of -17 is:
y=-4x-17.
