How can i find a form for y= mx + b using (200, 100) and (50,25)

The answer is

Step-by-step explanation:

Formula:

We first need to find the slope:

Now we need to find the y-intercept:

y = mx + b (substitute)

100= 7/2(200) + b

100 = 700 + b

-700=-700

-600 = b

Using the information we now have:

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)
