Write a linear equation from two points. Math Grade 8 Curriculum Map. Students know that those numbers x that satisfy a given equation are called solutions.
Using what you know about the words linear from Lesson 2 and equation from Lesson 1 develop a mathematical definition of linear equation in 𝑥 Show students the examples below and provide them time to work individually or in small.
In Module 4 students use similar triangles learned in Module 3 to explain why the slope of a line is well-defined. Here is a linear equation in x. Students know that a linear equation in x is actually a question. Can you find all numbers x if they exist that satisfy a given equation.
