First, rewrite the equation in the "slope-intercept" form: y = mx+b:
x%2B2y+=+3 Subtract x from both sides of the equation.
2y+=+-x%2B3 Now divide both sides by 2 to get the y by itself.
y+=+%28-1%2F2%29x%2B3%2F2 Compare this with the general form of the slope-intercept:
y+=+mx%2Bb and you can see that the slope,highlight%28m+=+%28-1%2F2%29%29 and the y-intercept, highlight%28b+=+3%2F2%29
