Question

How do you graph `3x - 2y = 6` by plotting points?

Answer 1

Use graph paper or a spreadsheet program to calculate (x,y) pairs of solutions and place them on the graph.

Explanation:

This will be facilitated by first rearranging the equation into one that show a direct relationship between ‘x’ and’y’.
`3x − 2y = 6` ; `-2y = 6 – 3x` ; `y = -3 + (3/2)x` ; `y = (3/2)x - 3`
