Write the equation for the linear function that goes through –3 on the y-axis and has a slope of 0.5.
vazorg [7]

Answer: y = \frac{1}{2} x - 3

Step-by-step explanation:

  1. The equation for a line is in the form y = mx + b, where "m" is the slope and "b" is the y-intercept.
  2. Since the slope is 0.5 (which is \frac{1}{2}), we can plug that value in for "m": y = \frac{1}{2} x + b
  3. Since the line goes through -3 on the y-axis, that is the y-intercept. So, we can just plug in that value for "b": y = \frac{1}{2} x - 3
  4. And there's your answer: y = \frac{1}{2} x-3
