What we need to do first, is to write the equation of the line through points A and B.
the slope of the line through A(3, 7) and B(-4, 9) is

the equation of the line is :

C(a, 1) is on this line so it must satisfy the equation:
Answer:
I think B
Step-by-step explanation:
Answer: X<Y, X>0
Because -4 is less than 0 and -4 is greater than 0
