Let's check our answer. So our m is equal to 2.
And they tell us what g of 0 is. Divide both sides of this equation by 3. And let me just verify that that's what I did there. And there's really two things that we need to figure out.
On this page, you will find worksheets on making a table and plotting points given a unit rate, graphing whole number functions, function tables with two-step rules, writing a function rule given a table of ordered pairs: one-step rules, graphing a line in quadrant 1, interpreting a line graph, finding outputs of a one-step function that models a real-world situation, finding outputs of a two-step function with decimals that models a real-world situation, writing and evaluating a function that models a real-world situation, graphing ordered pairs and writing an equation from a table of values in context, writing an equation and drawing its graph to model a real-world situation, identifying independent and dependent quantities from tables and graphs, and so on.
And so they give us, for each x-value, what f of x is and what g of x is. And we got it right. If a car typically gets 20 mpg, and if you input 10 gallons of gasoline, it will be able to travel roughly miles.
