Question

Work out the equation of the line which has a gradient of 12 and

passes through the point (4, -2).

Answer 1

Explanation:

Equation of line in slope point form is given as:

`y - y_1 = m(x - x_1) \\ \therefore \: y - ( - 2) = 12(x - 4) \\ \therefore \: y + 2 = 12x - 48 \\ \therefore \: 12x - y - 48 - 2 = 0 \\ \therefore \: 12x - y - 50 = 0 \\ which \: is \: the \: equation \: of \: \: required \:\\line.`
