Question 63548
In each case, do whatever you have to do to get the 
equations in the form {{{y = mx + b}}} where m = slope
{{{3x + 5y = 1}}}
subtract 3x from both sides
{{{5y = -3x + 1}}}
divide both sides by 5
{{{y = (-3/5)x + 1/5}}}
{{{m = -3/5}}} answer
You do roughly the same to the other equations
