How do you graph the line #-4x - 16y = 4#?
The easiest way is to manipulate the equation into the form of
The assign different values to x from which you can then calculate the corresponding value for y. For a straight line graph you only need two points that you can join up and extend to give the graph plot. How ever, 3 points are better as it increases the chance of showing up any error. All 3 points should line up.
To make the
Subtract #color(blue)(4x) from both sides
Divide both sides by 16
