Transcript text: Are the two lines parallel, perpendicular, or neither? Choose one $\cdot$ 1 point
Solution
Solution Steps
Step 1: Identify the slopes of the lines
To determine if the lines are parallel, perpendicular, or neither, we first need to identify the slopes of the two lines. The slope of a line in the form \( y = mx + b \) is given by \( m \).
Step 2: Determine the slope of the blue line
From the graph, the blue line passes through the points \((0, 5)\) and \((5, 10)\). The slope \( m \) is calculated as:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{10 - 5}{5 - 0} = \frac{5}{5} = 1 \]
Step 3: Determine the slope of the red line
From the graph, the red line passes through the points \((0, -5)\) and \((5, 0)\). The slope \( m \) is calculated as:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - (-5)}{5 - 0} = \frac{5}{5} = 1 \]
Step 4: Compare the slopes
Since both lines have the same slope \( m = 1 \), they are parallel.
