The graph has a greater rate of change.*** The table has a greater rate of change. none of the above 2. y = 2x + 7 The slopes are equal. The graph has a greater slope. The equation has a greater slope.*** none of the abov 3. As x increases by 1, y increases by 3 The slopes are equal. The graph has a greater slope. Let's take a look at another example that does not involve a graph. Example 2: Rate of Change. In 1998, Linda purchased a house for $144,000. In 2009, the house was worth $245,000. Find the average annual rate of change in dollars per year in the value of the house. Round your answer to the nearest dollar. Determine, to the nearest tenth, the average rate of change from day 50 to day 100. 3 The graph of f(t) models the height, in feet, that a bee is flying above the ground with respect to the time it traveled in t seconds. State all time intervals when the bee's rate of change is zero feet per second. Interpretation. As noted above, the Rate-of-Change indicator is momentum in its purest form. It measures the percentage increase or decrease in price over a given period of time. Think of it as the rise (price change) over the run (time). In general, prices are rising as long as the Rate-of-Change remains positive.
Miles per hour is a rate. What interest does your savings account pay you? Interest paid / year is a rate. Rate of change[edit]. This graph shows how John's savings account balance has changed over the course of a year. We can see that he opened his account with $300 and by the end
A rate of change is a rate that describes how one quantity changes in relation to another quantity. rate of change = change in y change in x = change in distance change in time = 160 − 80 4 − 2 = 80 2 = 40 1. The rate of change is 40 1 or 40 . This means a vehicle is traveling at a rate of 40 miles per hour. Which function has the greatest rate of change on the interval from x = π to x = 3 pi over 2 What are the sine, cosine, and tangent of 11 pi over 6 radians? Compare each of the functions shown below: Practice: Average rate of change: graphs & tables. Next lesson. Average rate of change word problems. Worked example: average rate of change from graph. Average rate of change: graphs & tables. Finding the average rate of change …
To find the greatest rate of change of the graph we will find the slope of each graphs. Option A. Points lying on the line are (0, 0) and (4, 1) Therefore slope = Option B. Points lying on the graph B are (0, 0) and (1, 4) therefore slope of the line = Option C. Points lying on the graph are (0, 0) and (2, 1) slope = Option D. Look at the slope in the example below and compare it to Example 2 above. Which slope is steepest? Which shows the greatest rate of change? Both graphs show a decline of $50 per month. They both show the same rate of change. It is only the difference in scale of the y-axis that makes Example 2 appear steeper. So (b) has the greater rate of change Now let's put it all together. What if we are given a graph, an equation, and a table? y = 9x + 3 x y 2 12 4 18 6 24 a) b) c) * Remember: rate of change = slope = rise run m = 4 1 m = 9 m = 3 b) has the greatest rate of change.

The rate of change is the rate at which y-values are changing with respect to the change in x-values. To determine the rate of change from a graph, a right triangle is drawn on the graph such that
