Consider the linear equation 2x−y+1=0.
a. (i) Prepare a table of values by choosing any three convenient values of x and writing the corresponding values of y.
b. (ii) Plot the points obtained in the table on a Cartesian plane and draw the straight line passing through them.
c. (iii) Using your graph, write the coordinates of the points where the line meets (a) the x-axis and (b) the y-axis.
d. (iv) Verify algebraically whether the point (3,7) lies on the line and cross-check your conclusion with the graph.
