Question

Find the equation of the line with a slope of -1/2 through (4,5)
Please answer fast

Answer 1

Answer:

We use method of finding gradient of which we are given the the gradient (-1/2)

(y-5)/(x-4) = -1/2

Removing fraction

2(y-5) =-1(x-4)

Removing brackets

2y - 10 = - x + 4

Making coefficient of (y) unit (divide everything by 2)

y - 5 = - (1/2)x +2

Making (y) subject of formula

y = - (1/2)x + 7 (answer)
