The lp relationships that follow were formulated by richard martin at the long beach chemical company.
maximize 8x1 + 0.5x1 x2 + 5x3
subject to: 1x1 x2 + 2x3 ≤ 70 (c1)
10.9x1 - 4x2 ≥ 156 (c2)
5x1 + 3x2 + 3x3 ≥ 21 (c3)
16x2 - 0.33x3 = 17 (c4)
-7x1 - x2 + 4x3 = 5 (c5)
1x1 + 2x2 + 3squareroot of x3 ≤ 80 (c6)
for an lp, the objective function developed by richard is valid or invalid
constraint c1 is(n) valid or invalid
constraint c2 is(n) valid or invalid
constraint c3 is a(n) valid or invalid
constraint c4 is a(n) valid or invalid
constraint c5 is a(n) valid or invalid
constraint c6 is a(n) valid or invalid

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?
