Write the equation of the line with x-intercept (12, 0) and y-intercept (0, 4).


We know two points on the line, hence we can find its' gradient.

gradient = (difference of y co-ordinates)/(difference of x co-ordinates)

gradient =  = 

We know the gradient, 

Using the following formula, we can find out the equation of the line.

y - example y co-ordinate = gradient x (x - example x co-ordinate)

We will use (12,0)

y - 0 = (-1/3) x (x-12)

y =
