Can someone please explain to me how to solve this and problems like this in the easiest way possible

as you can see, the "b" part is -5, or namely the y-intercept is at (0 , -5).

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

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)
