• Change in Y's

• Y-intercept

The amount of snow that falls during a snowstorm is shown on the graph. Find and interpret the rate of change and initial value. Then write the equation of the function in the form y = mx + b

The table shows the amount of flour remaining after baking loaves of banana bread. Assume the relationship between the two quantities is linear. Find and interpret the rate of change and initial value. Then write the equation of the function in the form y = mx + b

The table shows the temperature of an oven as it preheats. Assume the relationship between the two quantities is linear. Find and interpret the rate of change and initial value. Then write the equation of the function in the form y = mx + b

The table shows the amount of water that leaks from a pool. Assume the relationship between the two quantities is linear. Find and interpret the rate of change and initial value. Then write the equation of the function in the form y = mx + b

The table shows the battery life of a flashlight. Assume the relationship between the two quantities is linear. Find and interpret the rate of change and initial value. Then write the equation of the function in the form y = mx + b
