Question

What is the equation of a line with a slope of –2 that passes through the point (6, 8)?

Answer 1

y = mx + b
slope(m) = -2
(6,8)...x = 6 and y = 8
now we sub and find b, the y int
8 = -2(6) + b
8 = -12 + b
8 + 12 = b
20 = b
so ur equation is : y = -2x + 20

Answer 2

Answer with explanation:

Slope of Line= -2

The line passes through the point , (6,8).

⇒Equation of line passing through point , (a,b) having slope ,m is

y -b = m (x -a)

⇒≡Equation of line passing through point , (6,8) having slope ,-2 is

→y -8 = -2× (x -6)

→y -8 = -2 x + 12⇒⇒ Using Distributive property of multiplication with respect to Subtraction

→2 x + y= 12 + 8

→2 x + y=20

Required Equation of line.
