3.2 Linear Programming 3 Credits AS 91574

2
I can plot linear equations I can find the points of intersection

3
try these... Draw axes with x from -4 to 4 and y from -8 to 6 Then plot the following graphs on the same axes… a) y=3x-4 b) y=2x+1

4
You need 3 points to plot a straight a good start can be x = 0 and y = 0 for y = 2x + 1 this gives (0, 1), (-0.5, 0) and at random choose x = 1 (1, 3) with y = 3x - 4 (0, -4), (-1.3, 0) and (1, -1)

5

6
This time you need to rearrange the formula first (unless you can do it in your head?) a good start can be x = 0 and y = 0 for 2y = x + 10 rearranges to y = 0.5x + 5 which gives (0, 5), (-10, 0) and (almost) at random choose x = 2 (2, 7) with 0.5y = x – 2.5 rearrange to get y = 2x - 5 (0, -5), (-2.5, 0) and (3, 1)

8
Finding points of intersection use your calculator! select Equations, Simultaneous and two unknowns just like you did for 3.15! 188x + 290y = 2315 120x + 400y = 1800 should give you x = 10 and y = 1.5
