Question 1164646
<br>
x-intercept, (a,0).  Set y=0 and solve for a.<br>
y-intercept, (0,b).  Set x=0 and solve for b.<br>
a) {{{((x-2y))/3-12=((2x+4y))/3}}}<br>
x-intercept, (a,0).<br>
{{{a/3-12=2a/3}}}
Solve for a.<br>
y-intercept, (0,b).<br>
{{{-2b/3-12=4b/3}}}
Solve for b.<br>
b) {{{6x+3y=-36}}}<br>
x-intercept, (a,0).<br>
{{{6a = -36}}}
Solve for a.<br>
y-intercept, (0,b)<br>
{{{3b = -36}}}
Solve for b.<br>
c)  The two x-coordinates are the same; the y-coordinates are different.  The line is vertical; its slope is undefined.<br>
NOTE: Don't say "no slope" -- that makes it sound as if the slope is 0.<br>
