Question

Write an equation of the line that passes through (8, 3) and (4, 3)
A. y = 3
B. y = 4x + 3
C. y = 4
D. y = 3x

Answer 1

The y coordinates are both points are 3, which means what?

Answer 2

I think is A ;)

Answer 3

find the gradient of the line

\[m = \frac{(3 -3)}{8-4)} = 0\]

the gradient of the line is 0 so the line is horizontal and parallel to the x axis.

using the point slope with either point

y - 3 = 0(x - 4)

y - 3 = 0

or y = 3
