Consider the straight line given by the equation 3x−2y+6=0.
(i) Define the terms slope, x-intercept and y-intercept of a straight line in the Cartesian plane.
(ii) Rewrite the given equation in the form y=mx+c and hence state the slope and the y-intercept of the line.
(iii) Find the x-intercept of the line and explain why the two intercepts are sufficient to determine the complete graph of the line.
