Write and Solve a System of Equations
... Now substitute –15 for y in either equation to find the value of x. –3x + 4y = 12 First equation –3x + 4(–15) = 12 Replace y with –15. –3x – 60 = 12 Simplify. –3x – 60 + 60 = 12 + 60 Add 60 to each side. –3x = 72 Simplify. Divide each side by –3. x = –24 ...

... F-IF.4. For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is i ...
