Transcript text: The equation of the line is: $\square$
Solution
Solution Steps
Step 1: Identify Two Points on the Line
From the graph, identify two points that the line passes through. Let's choose the points (0, -5) and (5, 0).
Step 2: Calculate the Slope (m)
Use the slope formula \( m = \frac{y_2 - y_1}{x_2 - x_1} \):
\[ m = \frac{0 - (-5)}{5 - 0} = \frac{5}{5} = 1 \]
Step 3: Use the Point-Slope Form to Find the Equation
Use the point-slope form of the equation of a line \( y - y_1 = m(x - x_1) \) with one of the points, say (0, -5):
\[ y - (-5) = 1(x - 0) \]
\[ y + 5 = x \]
Step 4: Simplify to Slope-Intercept Form
Solve for \( y \) to get the equation in slope-intercept form \( y = mx + b \):
\[ y = x - 5 \]
