Question

Find the equation of aline whose slope is 4 and which passes through point(5,-7)

Answer 1

we know that a equation of line passing through the point having slope m can be written as
(y-y1) = m(x-x1)
according to question
m=4 and x1 = 5 and y1 = -7
then equation will be
y+7= 4(x-5)
i.e. 4x-y = 27
