Question

Please help please!! I’m in 8th grade

Answer 1

Y=mx+c

M=y1-y2/x1-x2
=26-79/45-40
=-1.3

Y=-1.3x+c

Replace any pair of x and y values in equation to get c

79=-1.3(5)+c
79+1.3=c
c=80.3

Y=-1.3x+80.3

Id choose the first option even tho the answer i did isnt up there but im guessing c is different for each point, but the slope is the same
