The parent, solid line function is y = log(x), and the dashed line function has been translated five units upwards. That means that the answer must be y = log(x) + 5
⇒To get the difference we subtract.

Goodluck!!
Firs t subtract seven then divide negative three and you get y= -3x+3/7 so -3 is your slope
If you meant -3x then the answer is (2,12)
