Question 1206846
<pre>
{{{drawing(400,400,-8,8,-8,8,

grid(1), line(10,24,-10,-36) )}}} 

That's the same as asking "What value of x causes y to be 0?

That's also the same as asking "At what x-value does the point on the x-axis 
have where the graph crosses it?"

Or, what is the x-intercept?

It's a look-and-see question. So look and see.
