Answer is A
Just make sure you do know how to do them :)
I did the math and I believe the answer is, the y-intercept is 12.3.
<h2>Greetings!</h2><h3>Firstly, the slope is found by rearranging the formula:</h3>
3y = 4x + 39
y =
+ 
When x is 0, y = 0(x) +
, so the y intercept is 
<h3>Next, the slope is simply the number in front of the x, </h3>
So
can be rearranged to
, so the slope would be
.
