Question 14797
There are two ways you can find the x-intercept of this equation.

1) You can graph the line and see where it crosses the x-axis.  See the graph below.

2) You can set y = 0 in the equation and solve for x.  This would be easier.

{{{4x + y = 4}}} Set y = 0
{{{4x = 4}}} Divide both sides by 4.
{{{x = 1}}} The x-intercept is at (1, 0)
