Question

What linear equation represents the graph of a horizontal line, parallel to the x-axis, that travels through the point (0,4)? Use the grid or a piece of paper if needed. LY 2 1 X 5 2 2 0 1 2 3 4 1 -2

Answer 1

It's important to know that all horizontal lines can be represented as y = k, where k is a real number.

In this case, we know that the horizontal line passes through (0,4).

Therefore, the equation of the line is y = 4.
