Question 240813
transform to slope intercept form: 
<pre>

       2x + 5y = 15
      -2x       -2x
     ---------------
            5y = 15 - 2x

Write the second term first on the right:

            5y = -2x + 15

Divide every number by 5

           {{{5/5}}}y = {{{-2/5}}}x + {{{15/5}}}

Simplify:
                         {{{3}}}              
          {{{cross(5)/cross(5)}}}y = {{{-2/5}}}x + {{{cross(15)/cross(5)}}}

            y = {{{-2/5}}}x + 3

That's the slope-intercept form,

            y = mx + b 

where the slope is m, which equals {{{-2/5}}}, and
the y-coordinate of the y-intercept is b, which equals 3.
That means the y-intercept is the point (0,3).
