Question 94367
Find the x-intercept:
{{{2x-5y = 20}}}
The x-intercept is where the graph of this linear equation intersects (crosses) the x-axis.  At this point, y is zero, so by setting y = 0 in the equation and solving for x, you will get the value of x where the line crosses the x-axis, also known as the x-intercept. So we'll set y = 0.
{{{2x-5(0) = 20}}}
{{{2x = 20}}} Divide both sides by 2.
{{{x = 10}}} This is the x-intercept!  This is clear from the graph of the linear equation.
