28.50x + 110.99(14-x)=811.45
distribute
28.50 x + 1553.86-110.99x =811.45
combine like terms
-82.49x+1553.86=811.45
subtract 1553.86 from each side
-82.49x =-742.41
divide by -82.49
x=9
He bought 9 of the 28.50 features and 5 of the 110.99 features
Slope intercept form is y = mx + b where m is slope and b is y intercept.
The line crosses the y axis at y = 4
The slope is 4/3
So the answer is y = (4x/3) + 4
