To graph the equation \( x - y = 6 \) using the slope-intercept form \( y = mx + b \), we first need to rearrange the equation.
-
Start with the original equation: \[ x - y = 6 \]
-
Solve for \( y \): \[ -y = -x + 6 \] \[ y = x - 6 \]
Now, we can see that this is in the form \( y = mx + b \) where \( m = 1 \) (the slope) and \( b = -6 \) (the y-intercept).
Steps to graph the equation:
-
Y-Intercept: Start by plotting the y-intercept (0, -6) on the coordinate plane. This is where the line crosses the y-axis.
-
Slope: The slope \( m = 1 \) means that for every 1 unit you move to the right on the x-axis, you move 1 unit up on the y-axis. From (0, -6), the next point can be (1, -5).
-
Plot another point: Continuing from (1, -5), we can go to (2, -4).
-
Draw the line: Draw a straight line through the points you plotted (0, -6) and (1, -5) and extend it in both directions.
Final Graph
You would see an upward slanting line starting from (0, -6) and increasing as you plot more points according to the slope.
