Question

The line given by y = 5x + 4 crosses the x-axis when x = ? Give your answer in fraction form.

Answer 1

The line y = 5x + 4 crosses the x-axis when x = -4/5.

Step-by-step explanation:

The line y = 5x + 4 crosses the x-axis when y = 0 because on the x-axis, the y-coordinate is 0. So, we set y = 0 in the equation and solve for x:

0 = 5x + 4

5x = -4

x = -4/5

Therefore, the line crosses the x-axis when x = -4/5.
