Homework Equations
So I got the constraints to be
1.x+y(less than or equal to) 275
2.225x+250y (less than or equal to) 63,000
3. x and y (Greater than) 0
So if the line from point A is extrapolated, then where it hits the x-axis would be constraint 2 and point C is constraint 1.
The Attempt at a Solution
The graph I ended up with:

You have a sign wrong in the right side. Solving the second equation for y gives y = -(225/250)x + 63000.hyde2042 said:Whoops. Sorry about the wrong post.
When I set the two equal to each other. -x + 275 = (225/250)x + (63000/250) I'm getting the incorrect answer.

I keep getting (12.1, 262.9)
In order to find point D on a graph, you will need to know the coordinates of at least two other points. Use the slope formula or the distance formula to calculate the missing coordinate.
When finding a point on a line, you can use the slope formula or the equation of the line to determine the coordinates. However, when finding a point on a curve, you may need to use calculus and derivatives to find the slope at a specific point, which can then be used to find the coordinates.
No, in order to accurately find point D, the two points you use must be on the same line or curve. Otherwise, the calculated coordinates of point D may not be correct.
Yes, finding point D on a three-dimensional graph requires using the distance formula in three dimensions. You will need to know the coordinates of at least three points in order to accurately find the coordinates of point D.
Yes, most graphing calculators have functions that allow you to input the coordinates of two points and calculate the coordinates of a third point. However, it is still important to understand the mathematical concepts behind finding a point on a graph in order to accurately interpret the results given by the calculator.
