Math Problem Statement

Write the equation of the line that passes through the points left parenthesis, minus, 5, comma, 1, right parenthesis(−5,1) and left parenthesis, 3, comma, 1, right parenthesis(3,1). Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line.

Solution

To find the equation of the line passing through the points (5,1)(-5, 1) and (3,1)(3, 1), let's proceed step by step:

Step 1: Determine the slope

The slope mm of the line is calculated using the formula: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1} Substitute (x1,y1)=(5,1)(x_1, y_1) = (-5, 1) and (x2,y2)=(3,1)(x_2, y_2) = (3, 1): m=113(5)=08=0m = \frac{1 - 1}{3 - (-5)} = \frac{0}{8} = 0

Step 2: Identify the nature of the line

Since the slope is 00, this indicates a horizontal line. For horizontal lines, the yy-value remains constant.

Step 3: Write the equation

The yy-coordinate for both points is 11, so the equation of the line is: y=1y = 1

Final Answer:

The equation of the line in simplified form is: y=1y = 1
