Question

Through (1,6) and (5,2) use function notation

Answer 1

yeah so

Answer 2

find slope using slope formula (y1-y2)/(x1-x2)=(6-2)/(1-5)=4/-4=-1 so slope is -1

Answer 3

now substitue point in y=-x+b
2=-5+b b=????????

Answer 4

sorry I stepped away for a moment.

Answer 5

B=7

Answer 6

yeah

Answer 7

so the final equation is y=-x+7
