Let's learn how to write equations to describe functional relationships.
TEKS Standards and Student Expectations
A(2) Linear functions, equations, and inequalities. The student applies the mathematical process standards when using properties of linear functions to write and represent in multiple ways, with and without technology, linear equations, inequalities, and systems of equations. The student is expected to:
A(2)(C) write linear equations in two variables given a table of values, a graph, and a verbal description
Given a problem situation in verbal form, students will write an equation that can be used to represent the situation.
What kinds of strategies can be used to identify the starting point and rate of change when given a problem situation?
When should slope-intercept form be used to write an equation for a problem situation?
When should standard form be used to write an equation for a problem situation?
