write the equation of the line with slope -2 and y-intercept (0,0).
:
It's just y = -2x
:
If you use the point/slope equation: y - 0 = -2(x - 0), y = -2x
:
Then the graph the line.
Solve the following system of linear inequalities by graphing.
3x+4y<12
4y < -3x + 12
y < (-3/4)x + 12/4
y < (-3/4)x + 3; plot this graph from x = 0 to x = +6
:
x + 3y < 6
3y < -x + 6
y < (-1/3)x + 6/3
y < (-1/3)x + 2; plot this graph from x = 0 to x = +6
x>0
y>0
It should look like this
:
The area of feasibility is below the lowest line, but positive x & y
The corners of this area are: 0,0; 4,0; 0,2; and at the intersection 2.4, 1.2
