Answer the following questions about the interpretation of a straight-line equation.
(i) Define (a) the slope and (b) the y-intercept of a straight line in the Cartesian plane.
(ii) Describe, step by step, how you can obtain the slope and the y-intercept from the general form Ax+By+C=0 when B=0.
(iii) Using your description in part (ii), obtain the slope and the y-intercept of the line 3x−2y+6=0, showing all intermediate steps.
