if: 6x - 7y = 10 then -7y = 10 - 6x y = 6x/7 - 10/7 The slope is now the coefficient of x, which is 6/7.

From first equation y = 3x + 5. Substitute this in second equation 2(3x + 5) = 6x + 10 This proves that 6x + 10 = 6x + 10 which is not helpful! I suppose possible solutions would be x = 0, y = 5 or x = 1, y = 8 etc etc Are you sure of your two equations, please?

6x = 10-y y = -6x+10 The slope is -6 and the y intercept is 10
If you mean: y = 6x-4 then the parallel equation is y = 6x+10
if: 6x - 7y = 10 then -7y = 10 - 6x y = 6x/7 - 10/7 The slope is now the coefficient of x, which is 6/7.

-6x + y = 9 (+6x) -> y = 6x + 9
y=6x-9
