The answer I think is-B,C,E plase tell me if im wrong.
Answer: -15
Solving Steps:
x + 1 / 5 = 2 + 3 (x - 1) / 10
x +1 / 5 = 2 + 3x - 3 / 10
2 (x + 1) = 20 + 3x - 3
2x + 2 = 17 + 3x
2x - 3x = 17 - 2
-x = 15
x = -15
Equation of line is y=mx + c
where c is y-intercept and m is slope.
Sub (3,1) and slope into equation:
1 = -2(3) + c
1 = -6 + c
c = 7
Thus, equation is y = -2x + 7
Ans is (a)
