<p>y=4x-9</p>

<p>An equation of a line in the xy-plane is given above. What is the x-coordinate of the point on the line for which the y-coordinate is 1 greater than the x-coordinate? Thanks :-P </p>

<p>tried to use my calculator but that didn't help much lol</p>

<p>(x+1)=4x-9
-3x=-10
x=10/3</p>

<p>Check:
y=(40/3)-9
y=13/3</p>

<p>Wow, can’t believe it was that easy I didn’t think to change the y to an x value. :-(</p>
