What is the y-intercept of the line with a slope of -7 that passes through the point (-1,-5

-12

Step-by-step explanation:

Slope-intercept form of a line is y=mx+b where m is the slope and b is the y-intercept.

We are given m=-7 and a point (x,y)=(-1,-5) in on the line.

Entering this information into y=mx+b, we will be allowed enough information to find the y-intercept, b.

y =mx+b with m=-7 and (x,y)=(-1,-5):

-5=-7(-1)+b

-5=7+b

Subtract 7 on both sides:

-5-7=b

-12=b

So the y-intercept is -12.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
