Algebra: Chapter 7, Lesson 6, page 328 Finding an Equation of a Line There are 2 ways that we can find an equation of a line. However, we need to have at least 2 points `(x,y)` or 1 point `(x,y)` … Continue reading →

Algebra: Chapter 7, Lesson 5, page 323 Equations and Slope An equation `y=mx+b` is called the slope-intercept equation of a line. The slope is `m` and the y-intercept is `b`. Without having to plot points, or make a T chart, … Continue reading →

Algebra: Chapter 7, Lesson 4, page 318 Slope of a Line The slope of a line is the tilt or slant. The slope is defined as the letter `m` and `m=(rise)/(run)`, where the `rise` is the change in the y-coordinate … Continue reading →

Algebra: Chapter 7, Lesson 3, page 313 Linear Equations and their Graphs Linear equation have to have variables with a power of 1, NO mixed variable products and NO variables in an equation in the denominator. The easiest way to … Continue reading →

Algebra: Chapter 7, Lesson 2, page 309 Graphing Equations We can graph an equation, by building a T-chart of values for both x and y. You can choose any values for `x ` and `y` when making your T-chart. I … Continue reading →
