Question

A line has a slope of 9 and passes through (0, -3). Write the equation of the line

Answer 1

Pick below

Explanation:

Using point(0,-3) slope (9) form the line equation will be :

(y- -3) = 9(x-0)

y +3 = 9x to convert to y = mx+b form, subtract 3 from both sides)

y = 9x-3 to convert to 'standard(?) 'form subtract 9x from both sides

y - 9x = -3 or , by multiplying by -1 : 9x -y = 3
