Question

Choose the equation of the horizontal line that passes through the point (2,4)

Answer 1

y=4

Explanation:

Since this line has the slope of 0 and y intercept of 4, its equation becomes y=4 for all real values of x

Answer 2

y = 4

Explanation:

The point (2, 4) has the x intercept = 2 and y intercept = 4.

A horizontal line has a slope of 0, therefore every point on a horizontal line has the same value and a slope of 0.

So to find the equation of the horizontal line, we use the value of y intercept which can be written in the form y = b where point is (a, b).

Since the point given here is (2, 4), therefore the equation of the horizontal line which passes through it will be y = 4.
