Points:
(-2, 3) and (3, 0)
------------------------------------------------
Find the slope:
------------------------------------------------
Slope Intercept Form:
y = mx + b
m = slope
b = y-intercept
Slope = -3/5
Y-intercept = 9/5
Answer: y = -3/5 + 9/5
------------------------------------------------
Point Slope Form:
y - y1 = m(x - x1)
You can use either of the points.
Answer:
y - 3 = -3/5(x - 2)
or
y - 0 = -3/5(x - 3)
------------------------------------------------
Hope This Helped! Good Luck!
Answer:
A. -12
Step-by-step explanation:
A graph shows the vertices of the feasible region to be (0, 6), (3, 0) and (0, -3). Of these, the one that minimizes f(x, y) is (0, -3). The minimum value is ...
f(0, -3) = 3·0 + 4(-3) = -12

<em>Comment on the graph</em>
Here, three regions overlap to form the region where solutions are feasible. By reversing the inequality in each of the constraints, <em>the feasible region shows up on the graph as a white space</em>, making it easier to identify. The corner of the feasible region that minimizes the objective function is the one at the bottom, at (0, -3).
