Write an equation for this graph in slope-intercept form

y = 3x + 5

y = 1/3 * x + 6

y = 6x + 1/3

y = 3x + 6

The slope intercept is (0,6)

1 answer

To confirm and derive a slope-intercept equation based on the details given:

Slope-Intercept Form

The slope-intercept form of a linear equation is given by: \[ y = mx + b \] where \( m \) is the slope and \( b \) is the y-intercept.

Given Information

  1. You provided multiple equations:

    • \( y = 3x + 5 \)
    • \( y = \frac{1}{3}x + 6 \)
    • \( y = 6x + \frac{1}{3} \)
    • \( y = 3x + 6 \)
  2. You mentioned "The slope intercept is (0,6)", which indicates that the y-intercept \( b = 6 \).

Identifying the Relevant Equation

Since the y-intercept at \( (0,6) \) indicates \( b=6 \), we can narrow it down to the equations that include \( b = 6 \):

  • \( y = \frac{1}{3}x + 6 \)
  • \( y = 3x + 6 \)

Conclusion

To write an equation for the graph that uses the y-intercept given, we can use either of the two equations identified:

  1. \( y = \frac{1}{3}x + 6 \) (slope of \( \frac{1}{3} \))
  2. \( y = 3x + 6 \) (slope of \( 3 \))

Final Answer

Based on the requirement for the slope-intercept form with a y-intercept of 6, both \( y = \frac{1}{3}x + 6 \) and \( y = 3x + 6 \) are valid. Choose one based on the slope preference.
