Question 175778
{{{y = -3x + 2}}}
You should just substitute the x and y into the equation
Any point contains (x,y). In this case,
the point is (3,-1), so
{{{x = 3}}}
{{{y = -1}}}
{{{y = -3x + 2}}}
{{{-1 = -3*3 + 2}}}
{{{-1 = -9 + 2}}}
{{{-1 = -7}}} not true
So, this point cannot be part of the solution
