Answer:
The solution is (8, -1).
Step-by-step explanation:
2x + 4y = 12..........(1)
y = 1/4x – 3 ..........(2)
Substitute y = x - 3 in equation (1):
2x + 4(1/4x - 3) = 12
2x + x - 12 = 12
3x = 24
x = 8.
Now substitute for x in equation (2):
y = 1/4 *8 - 3
y = -1.
Answer:
B
Step-by-step explanation:
B has a slope of 7 while A has a slope of 6.
slope of B 14-7/2-1 = 7
A slope is y= mx+b and m is the slope. so 6.
