Answer:
Step-by-step explanation:
Parallel to y=2÷3x+6
Passes through (6,7)
slope is (2/3)
Solve for when y is 7 and x is 6.
take out the + 6 at the end because it doesnt change the slope. replace with b. (y=mx+b)
replace y and x.
7 = (2/3)(6)+b
solve for b and then put it back into the equatio and make 6 and 7 into x and y again.
