First you would need to convert the equation to match the y = mx + b format.

Subtract 2x from both sides to get -y = -2x + 3

Then, divide -1 (because that's the coefficient to -y, on all values, turning to equation into
y = 2x - 3 (negative and negative makes a positive that's why the 2 value is now positive) in order to make the y value positive.

Our y intercept is -3 so start your graphing line on the -3 value on the x axis.

Our slope is 2/1 which means to go up 2 point and right 1 point, since it's a positive slope.

You can mark every point in order to get a more accurate line and just connect the dots from there. Be sure to use a ruler or some sort of straightedge for a better line.

Hope this helped :)
