3.4 Length & Midpoint

 Calculating the Length of the Line

To find the length of the starting coordinate and the ending coordinate of the line. Similar to gradient we will need two coordinates to figure out the length. The length formula is derived from the Pythogoras theorem formula. The diagram below demonstrates it.

 


As from the diagram above,  it creates a right-angle triangle. Hence, using a modified variation of the Pythogares theorem.


 Calculating the Midpoint of the Line

Similar to length a starting coordinate and ending coordinate of the line is required. The midpoint formula is in the coordinate format.

3.5 Parallel Lines & Perpendicular Lines

 Parallel Lines  In a graph, the properties of parallel lines share the same gradient. As the slope doesn't change m remains the same for both line equations. Perpendicular Line A perpendicular line is a line that bisects another line, going through the midpoint creating a right angle at the point of intersection  The formula to calculate the gradient for perpendicular line  As we have reached the end of the unit 3  Past Year Paper Questions

3.2 Drawing Linear Graph

  What is a Linear Graph? Linear the word itself means straight . This is a line drawn in a graph that has no curves. To draw the linear graph we have to plot coordinates.  Usually, an equation is given in the line equation format: The equation will always have 2 variables x and y. The linear equation will always have a positive x or a negative x.  When y=x ( positive)   When y=-x (negative) Some Special Cases  When:   y= 4 (Blue Line)    y= 1 (Green Line)    y= -2 ( Red Line)  When:   x= 4 (Blue Line)    x= 1 (Green Line)    x= -2 ( Red Line)    How to Draw a Linear Graph? The question would have an equation with 2 unknown variables x and y. Examples:  a) 2x-y=4 b) y-x=9 c) x= 3y-6 d) y= -7x-3 Step 1 : Check if the question gives a range such as  -4 ≤ x ≤ 4. This indicates x-axis should be from -4 to 4. Draw the x-axis and y-axis on graph paper accordingly. Step 2: Draw a table of value...
