Responses

y=−3x−3
y is equal to negative 3 x minus 3

−3x−y=3
negative 3 x minus y is equal to 3

y=3x−3
y is equal to 3 x minus 3

y=3x+3
y is equal to 3 x plus 3

1 answer

To determine the equation of the line in the form \( y = mx + b \), we need the slope (\( m \)) and the y-intercept (\( b \)).

Based on the responses you provided, if the slope is negative 3, the equation would be represented as \( y = -3x + b \). If the slope is positive 3, it would be \( y = 3x + b \).

Without seeing the graph, I can't specify the correct answer. However, you can determine the correct equation by:

  1. Identifying the slope of the line (rise over run).
  2. Finding the y-intercept (where the line crosses the y-axis).

Compare your findings with the provided options:

  • y=−3x−3 (slope = -3, y-intercept = -3)
  • −3x−y=3 (this can be rearranged but is not in y=mx+b form)
  • y=3x−3 (slope = 3, y-intercept = -3)
  • y=3x+3 (slope = 3, y-intercept = 3)

If you have the values or characteristics of the graph, you can now select the appropriate equation!
