I'm in a bit of jam. I need to solve the equation, abc=a for "a."?

It appears to me that solving for "a" is not possible. Is this a so-called "conditional equation"?

Can you do this co-ordinate geometry?

How would i determine the slope of the line with the equation:
5x-y=8

find the axes intercepts of the line with equation 3x-4y=-12

find b if (b,3) lies on the line with equation 2y-3x=15

Anything is appreciated and if anyone could show how they got the answer. Thanks in advance.
