Method 1 using two points to graph a linear equation The graph of any linear equation like y = 3 x 2 or y = − x 9 is a line, and only two points are needed to define a line The idea with this method is to find two points on the line by picking values of xAnd so y = 2x 1;Use the intercept method to graph xy=3 Step 1 Intercepts occur when one of the coordinates is equal to 0 So the yintercept occurs at x=0 and the xintercept occurs at y=0 Step 2 It takes two points to make a line So use these intercepts points Step 3 When x=0, then 0y=3 or y=3 So we have point (0,3) Step 4 When y=0, then x0=3 or
In example 3 look at the tables of values and note that for a given value of x, the value of y in the equation y = 3x 2 is two more than the corresponding value of y in the equation y = 3x Look now at the graphs of the two equations and note that the graph of y = 3x 2 seems to have the same slope as yThen click on the graph until the correct one is displayed 3 x y 1 = 0 / < It goes from the bottom left corner up into the top right corner Using graph paper, graph the following equation Then click on the graph until the correct one is displayed y = 3/5 x 12 (a) Complete the table of values for y = 1 – 2x (Total for question 2 is 5 marks) (b) On the grid draw the graph of y = 1 – 2 x for values of x from –2 to 3

For example, Use your graph to solve the equation x 2 x – 2 = 0 We have already drawn the graph for y = x 2 x – 2 The other side of our equation is zero, so we need to think about the line y = 0 This is the xaxis, so look for the points where the graph crosses the xaxis The solutions are x = 1 and x = 2 To solve the equation x 2 x – 2 = 3, we would draw the line y = 3 The graph of y = x − 3 is almost the same as y = x The difference is that every point on y = x has been lowered by 3 Thus, instead of the yintercept being at y = 0 it is at y = − 3 instead Consider the generic equation of y = mx c where m is the gradient (slope) If you compare this to both y = x and y = x − 3 you will observe that there is no value shown for m (1 point) x = 2, 0, 2, 4 y = 4, 0, 4, 8 The values do not show a linear function Yes, they show a linear Math The graph represents function 1 and the equation represents function 2 A graph with numbers 0 to 4 on the xaxis and yaxis at increments of 1 A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3
