This math video app provides a quick and simple way for you to learn and understand the basics behind linear graphs and equations. All of the 12 computer animated videos are stored in your device. So, no internet connection required to play. These math videos are: The coordinate plane, the coordinates of a point, graphing linear equations, the change in x & change in y, slope of a line, slope formula, positive slope & negative slope, the x-intercept & y-intercept, the slope-intercept form, slope-intercept form examples, determining the equation of a line, equation of lines parallel to the axes. Each of these videos is divided into several different parts that you can easily skipped to. More details below: 1. The coordinate planeIntroduction The x-axis or horizontal axis The y-axis or vertical axis The point of origin The four quadrants 2. The coordinates of a point Introduction Position of a point Read and write the x-coordinate and y-coordinate Example 1 & example 2 Example 3 & example 43. Graphing linear equations Introduction Graphing the equation y=2x+1 Finding the y-coordinate of the first point when its x-coordinate is 1 Plotting the first point Calculating and plotting the rest of the points4. The change in x & change in y Introduction The basics: First 'run' and then 'climb' Example 1: Calculating the 'change in x' Example 1: Calculating the 'change in y' Example 2: Calculating the 'change in x' & 'change in y5. Slope of a line IntroductionDrawing & visually examining the slope of a line Assigning a meaningful number to the slope How are 'change in x' and 'change in y' useful Exploring the slope of a line 6. Slope formula Introduction Slope is the ratio of 'change in y' to 'change in x' Deriving the slope formula An example on using the slope formula Another example on using the slope formula 7. Positive slope & negative slope Introduction Zero slope Positive slope Infinite slope Negative slope & more examples 8. The x-intercept & y-intercept Introduction Visual demonstration on the y-intercept Visual demonstration on the x-intercept Example 1: The x-intercept & y-intercept of y=2x+4Example 2: The x-intercept & y-intercept of 2x-4y=8 9. The slope-intercept form Introduction: What is the slope-intercept form? Demo on the slope-intercept form a line Visual demo on the y-intercept (b) Visual demo on the slope (m) when it is positive Visual demo on the slope (m) when it is zero or negative 10. Slope-intercept form examples Introduction Example 1: Draw the line of y=-2x+3 Example 1: Draw the line after analyzing m & b Example 2: Draw the line of 3y-2x=-6 Example 2: Draw the line after analyzing m & b 11. Determining the equation of a line Introduction Example 1: Determine the equation when a point and slope are given Example 2: Determine the equation when two points are given Example 2: Use the two points to find the slope (m) Example 2: Use one of the points to find the y-intercept (b) 12. Equation of lines parallel to the axes Introduction Understanding equation of the line parallel to the x-axis Understanding equation of the line parallel to the y-axis Example 1: The equation of a line that is parallel to the x-axis Example 2: The equation of a line that is parallel to the y-axis
