Understands initial value as the value of y when x is zero. Understands that initial value is found by substituting numeric values for the rate of change and the coordinates of an ordered pair into the equation for a line (y = mx + b, or equivalent) and then solving for b.

First you’d select two values from the table and plug them into the rate of change formula to get the rate of change

Then, you would calculate the value of the dependent variable (usually y) when the independent variable (usually x but not always) equals 0. This gives you the initial value. Sometimes this value will be given in the table.
