Passes through (2, -7), slope = 3

b= -13

Step-by-step explanation:

y=mx+b

-7=3(2)+b

-7=6+b

-7-6=b

-13=b

put it back into y=mx+b

y=3x-13

b=1, Y= -3-1

Step-by-step explanation:

y = -3 + b

-7 = -3(2) + b

-7 = -6 + b

add 6 on both sides

-1 = b

18.36. give me brainliest!

step-by-step explanation:
