Question

The line with the equation is graphed in the xy &#8209;plane. What is the x -coordinate of the x &#8209;intercept of the line?

Accepted Answer

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.
