Question 177189
First, rewrite the equation in the "slope-intercept" form: y = mx+b:
{{{x+2y = 3}}} Subtract x from both sides of the equation.
{{{2y = -x+3}}} Now divide both sides by 2 to get the y by itself.
{{{y = (-1/2)x+3/2}}} Compare this with the general form of the slope-intercept:
{{{y = mx+b}}} and you can see that the slope,{{{highlight(m = (-1/2))}}} and the y-intercept, {{{highlight(b = 3/2)}}}
