Question

Write an equation for the line that is parallel to the given line and passes through the given point.

Y=2x+4:(3,8)

A:y=2x+2
B:y=2x+6
C:-2x+6
D:Y=-1/2+2

Answer 1

Explanation:

Slope(m) = 2, P1(3,8), P2(x,y).

m = (y-8)/(x-3)

2 = (y-8)/(x-3)

Cross multiply:

2(x-3) = (y-8)

2x-6 = y-8

Eq: Y = 2x + 2.

Check: Y = 2*3 + 2 = 8.
