Question 1101641
You can graph the line using the y-intercept and the slope given in the equation and estimate if the point is on the line; however it is better to solve it algebraiclly. The most accurate and efficient way to solve this problem is the plug in the x-value (-1) and the y-value (5) into the equation and see if the equation is a true statement.

{{{y=-2x+3}}}
{{{(5)=-2(-1)+3}}}
{{{5=2+3}}}
{{{5=5}}}

You can conclude that (-1, 5) is a solution of that equation.
