The graph of a linear equation is a straight line To locate that straight line you just need two points To find a point, you give a value to one of the variables (x or y), and solve the equation to find the corresponding value for the other variable4/2 = (2/2)x 2 = x The point is (2, 0) shown with a brown dot At this point, you could make the graph with these 2 points when graphing linear equations, but it will not hurt to get one more So as we said, let x be anything, say 4, then y = 2 × 4 4 = 8 4 = 4 The third point is (4, 4) shown in red The graph is shown belowEquation of a line is y=2x a) A is a point on the line If the x coordinate of A is −2, find its y coordinate b) Verify whether a circle of radius 5 centred at A passes through the point B(5,5) c) Radius of a circle passing through B is 5 and its centre is on the above mentioned line Find the coordinates of its centre View solution Draw The Graph Of X Y 6 X Y 2 On The Same Graph And Find The Co Ordinates Of The Point Where Ma...
