Given the numerical equation:

y = 2x - 14

Determine the x-intercept.

Solution:

In order to determine the x-intercept, we simply needed to equate y to 0, then solve for x.

y = 2x - 14

0 = 2x - 14

Transpose -14 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

2x = 14

Divide both sides by 2 in order to determine the value of x.

2x/2 = 14/2

x = 7

Final answer:
x = 7
