If it’s in slope intercept I pretty sure the slope should be 5 because if y=mx+b and the m is slope then slope should be 5
So firstly, foil 3(4g + 6) and 2 (6g + 9): 
Now since the quantity is the same on both sides of this equation, this means that <u>this equation has infinite solutions.</u>
8m+3
Because sum means adding so you add 8m and 3
