Choose the equation of the vertical line passing through the point (8, −2). x = −2 y = −2 x = 8 y = 8

x = 8

Step-by-step explanation:

The general equation of a vertical line that passes through "a" is

.

Notice that x remains fixed at value "a" and y can take any value.

This can be understood by rewritting the above equation as

.

Then, the points ... (a, -2), (a, -1), (a, 0), (a, 1),(a, 2)... vertically aligned satisfy the above equations.

Now, returning to our specific exercise, we need the vertical line that passes through (8, -2). Since, the line is vertical, we have to focus on x-coordinate of the given point, and its value is 8.

Then, the equation of the vertical line passing through the point (8, −2) is

.

b. the decimal could be two-tenths.
