Question

Find the equation of the straight line passing through the point (0, 2)

Answer 1

Answer:

y = -4x+2

Step-by-step explanation:

y = x/4+5

y = 1/4(x+20)..........................1/4 is our gradient here

if parallel same gradient

if perpendicular, m1 *m2 = -1 ........where m1 is the gradient and m2 perpendicular gradient

1/4 * m2 = -1

m2 = -4

if passes through ( 0,2)

y-2 = -4(x-0)

y = -4x+2
