The slope is Y=5/3x.
A good trick to use to find the slope is count how high and how far you must go from one point to another to find the slope. (Rise over Run)
A equals 3
Equation is g(x)=3f(x)
What i did is notice the y intercept is at 3 so I plugged in x=0 into the parent equation and got f(0)=1
So to get this equation to the y=3 intercept which is the g function, you have to multiply it by 3

So 4/5 should be an 80 because if you multiply 5x20 and 4x20 you would get 80/100 but sometimes teachers make certain questions worth more points than others so maybe that is what happened but maybe talk to your teacher about it
