Comparing Standard and Slope-intercept Form
Standard form and slope-intercept form equations give you different ways of looking at a problem.
Example of Using Multiplication to Change Terms
Two different ways of using multiplication in a system of equations to eliminate a variable are demonstrated.
Examples Using Two Points to Write an Equation
Practice writing equations given two points on a line.
Solving Systems by Graphing
Graphing the solution to a system of slope-intercept form equations.
Using Intercepts to Graph Linear Equations
How to graph linear equations using intercepts.
Using Multiplication to Change Terms
How to use the multiplication property of equality to generate terms that are additive inverses so the elimination method can be employed to solve a system of equations.
Using Division to Change Terms
In addition to addition, subtraction, and multiplication, division can be used to change the numbers in a system.
Using Two Points on a Line to Write an Equation
Using the coordinates of two points on a line to write an equation involving the Celsius and Fahrenheit temperature scales.
Using Slope and One Point on a Line to Write an Equation
Writing an equation in slope-intercept form given the slope and a point on the line.
Using Slope-intercept Form to Graph an Equation
Using the slope-intercept form, the line can be graphed simply by plotting the y-intercept and using that slope to find the second point.
