Question 60700
In the equation x/2 + y/3 = 1, how do you find the x and y intercepts?
Let x=0 and solve for y to get the y-intercept.
{{{0/2+y/3=1}}}
{{{0+y/3=1}}}
{{{y/3=1}}}
{{{3*y/3=3*1}}}
{{{y=3}}}  The y-intercept is (0,3)
Let y=0 and solve for x to get the x-intercept.
{{{x/2+0/3=1}}}
{{{x/2+0=1}}}
{{{x/2=1}}}
{{{2*x/2=2*1}}}
{{{x=2}}}  The x-intercept is (2,0)
Here's what it looks like graphically, notice the line crosses the y axis at (0,3) and the x axis at (2,0).

Happy Calculating!!!
