To identify the slope and y-intercept from the equation \( y - 5 = -3x \), we can rewrite it in slope-intercept form (which is \( y = mx + b \)):
-
Start with the given equation: \[ y - 5 = -3x \]
-
Add 5 to both sides to isolate \( y \): \[ y = -3x + 5 \]
Now we can identify \( b \) (the y-intercept) and \( m \) (the slope):
- The y-intercept \( b \) is \( 5 \).
- The slope \( m \) is \( -3 \).
So for what you've asked:
- b (y-intercept): 5
- m (slope): -3
Now, let's summarize the answers:
- b: 5
- m: -3
To graph the equation \( y = -3x + 5 \), you would:
- Plot the y-intercept (0, 5) on the graph.
- From this point, use the slope \(-3\) (which means down 3 units for every 1 unit to the right) to plot another point.
Continue this process to graph the line!
