Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?

y = 2x – 2
y = 2x + 2
y = x + 2
y = x – 2

y = x + 2

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where

c represents the y intercept

m represents the slope of the line.

m = (y2 - y1)/(x2 - x1)

Line CD passes through (0, 2) and (4, 6),

y2 = 6

y1 = 2

x2 = 4

x1 = 0

Slope,m = (6 - 2)/(4 - 0) = 4/4 = 1

To determine the y intercept, we would substitute x = 0, y = 2 and m = 1 into y = mx + c. It becomes

2 = 1 × 0 + c

c = 2

The equation becomes

y = x + 2
