Write the point-slope form of the equation of the horizontal line that passes through the point (2, 1). a. Using variables, write out the formula for the point-slope form of the equation.

b. Identify the values for m, x1, and y1.

c. Fill these values into the point-slope form of the equation from part (a), and simplify as needed.

Use the box provided to submit all of your calculations and final answers. Simplify the answer as needed.

a. The formula for the point-slope form of a line is y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is a point on the line.

b. Since the line is horizontal, its slope is 0. Therefore, m = 0. The given point is (2, 1), so x1 = 2 and y1 = 1.

c. Plugging in the values into the point-slope form equation, we have y - 1 = 0(x - 2).

Simplifying, we get y - 1 = 0.

Therefore, the equation of the horizontal line that passes through the point (2, 1) is y = 1.
