Answer:
The required equation is 
Step-by-step explanation:
The equation of the given function can be written in the form
, where
is the slope and
is the y-intercept.
The given equation has a y-intercept of 
The straight line passes through
and
.
We calculate the slope using the formula,




We now substitute the slope and y-intercept into the above equation of the straight line to get,

This is the same as

First you set up your problem. You put the number you are dividing by on the left side of the thing you are dividing on. Then you put the number you are dividing. Try and follow the steps on the picture shown. Good Luck!!
