We can represent rates on a double number line to make predictions. A double number line represents rates, such as miles per hour, meters per second, or price per pound. Each pair of points on a double number line is an equivalent ratio. Using ratios and rates can help us solve problems. Equivalent ratios and equivalent rates keep the relationship between their terms the same. This property of equivalence is useful for solving problems with changing quantities and for predicting outcomes. All of the rates on a double number line are correct if the rates are equivalent to each other. We can check with division by dividing the top number by the bottom number. If all of the quotients are the same, the rates are correct. This video and its contents are the property of JoAnn's School and is protected under U.S. copyright law.

Given a word problem, we can use clue words from the problem to find the input variable x, the output variable y, the y-intercept b as the added condition, and the rate of change as the slope m. We can then write an equation in slope-intercept form to solve the problem. We walk-through three word problems and write equations in slope-intercept form that fit the problems. 8th Grade Math Course Playlist https://www.youtube.com/playlist?list=PLKi4WTp6PRGXnc3q2i4u3GMqVHYBFMz56 This video and its contents are the property of JoAnn's School and is protected under U.S. copyright law.
