Steel Company manufactures two kinds of wrought-iron rails: Model E (the elegant) and Model D (the distinctive). Model E rails sell for $59 and cost $50 to make, whereas Model
D rails sell for $48 and cost $41 to make. To make one Model E rail requires 2 hours on
Machine A, 1 hour on Machine B, and 4 hours on Machine C. On the other hand, to make
one Model D rail requires 1 hour on A, 2 hours on B, and 5 hours on C. Production
scheduling indicates that during the coming week Machine A will be available for at most
30 hours, Machine B for at most 24 hours, and Machine C for at most 72 hours. Find the
number of each kind of rail to be made in the coming week in order for the company to
maximize its profit. Calculate the maximum profit.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

they disappear if your absent from to long. i found out that the hard way.
