Answer:
C. 6x - 7y = 21
Step-by-step explanation:
y=2/3 x - 3, y-intercept = -3
A. 2/3 x + 3y = -3
3y = -2/3 x - 3
y = -2x - 1; y-intercept = -1
B.-2/3 x + 3y = 6
3y = 2/3 x + 6
y = 2x + 2; y-intercept = 2
C. 6x-7y=21
7y = 6x - 21
y = 6/7 x - 3; y-intercept = -3
D. x+4y = 12
4y = -x +12
y = -1/4 + 3; y-intercept = 3
Answer is C. 6x - 7y = 21
