Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?
2 answers:
(0,2)(4,6)
slope = (6 - 2) / (4 - 0) = 4/4 = 1
y = mx + b
slope(m) = 1
use either of ur points (0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 1(0) + b
2 = b
ur equation is : y = x + 2 <==
Answer:
The correct option is 3.
Step-by-step explanation:
If a line passing through two points then the equation of line is

It is given that CD passes through points (0, 2) and (4, 6), so the equation of line is



Add 2 on both the sides.

The equation of line CD is y=x+2. Therefore the correct option is 3.
