solve for k

j = hk

• jh = k

• j + h = k

• j - h = k

• j/h = k

How do you find the y intercept (initial value) of a graph?

• Find two points on the slope line, then Rise/Run

• Look to see where the slope line crosses the y axis

• Look to see where the slope line crosses the x axis

Suppose a graph has a slope (rate of change) of 6 and a yintercept (initial value) of 2. What would the equation be?
