Answer:
A. (3,2) . I recommend using desmos to find the coordinates
Answer:
Step-by-step explanation:
10x - 15y = 21
15y = 10x - 21
y = ⅔x - 7/5
slope of line is ⅔
slope of any perpendicular to line is -3/2
y = kx + k
slope of line is k
k = -3/2
ANSWER
See explanation.
EXPLANATION
Step 1
Graph each of the functions.

and

Step 2
Look for the point of intersection of the two graphs.
From the graph, the two functions intersected at
(0.38,6.14)
1 gal = 4 quarts
3 gal = 4 * 3 = 12 quarts
12 / 2 = 6 pitchers
