Question

Write the point-slope form of the equation of the horizontal line that passes through the point (2, 1). Include your work in your final answer.

Answer 1

y=1

Explanation:

When you have a horizontal line then you would have a slope that equals 0. Knowing this means you will not have a standard point-slope equation. Since (2,1) and the line is horizontal, the line will pass thru (0,1) and will look something like this.

Answer 2

2-1=1
y-y1=m(x-x1)
y-1=1(x-2)
