Explanation
The correct answer is 1.25. The y-coordinate of the x-intercept is 0, so 0 can be substituted for y, giving 
. This simplifies to 
. Multiplying both sides of by 5 gives 
. Dividing both sides of by 4 gives 
, which is equivalent to 1.25. Note that 1.25 and 5/4 are examples of ways to enter a correct answer.
