The given equation is in the slope-intercept form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept. For the equation \( y = 2x - 7 \):
Slope (\( m \)) = 2
Y-intercept (\( b \)) = -7
Step 2: Plot the Y-Intercept
Locate the y-intercept on the graph. The y-intercept is the point where the line crosses the y-axis. For \( y = 2x - 7 \), the y-intercept is -7. Plot the point (0, -7) on the graph.
Step 3: Use the Slope to Find Another Point
The slope of 2 means that for every 1 unit increase in \( x \), \( y \) increases by 2 units. Starting from the y-intercept (0, -7):
Move 1 unit to the right (x = 1)
Move 2 units up (y = -7 + 2 = -5)
Plot the point (1, -5) on the graph.
Step 4: Draw the Line
Draw a straight line through the points (0, -7) and (1, -5). This line represents the equation \( y = 2x - 7 \).
Final Answer
The graph of the line \( y = 2x - 7 \) is a straight line passing through the points (0, -7) and (1, -5).
