the given equations are
2x-3y=12 and

see our options
1st: both are in slop intercept form
no, slope intercept form is y =mx+b, the first equation is not in slope intercept form
2nd: niehter is slope intercept
nope, the 2nd one is in y=mx+b form
3rd: if we solve for y, we get

correct
4th one: wrong because 3x+5y=10 is not slope intercept
answer is 3rd option
