Question

A line which passes through the points(0,4) has gradient 5 write down the equation of a line

Answer 1

answer: y-4=5(x-0)
or, y-4 =5x
or, 5x -y +4 =0

Answer 2

m = (y - y1)/(x - x1)
Therefore, 5 = (y - 4)/(x - 0)
So, we get, 5x = y - 4
And 5x - y = -4
Therefore, the equation of the line is -
5x - y + 4 = 0
