Question

Which of the following is the equation of a line that passes through the points (2,5) and (4,3)?

A. y = -2x + 5
B. y = 2x + 5
C. y = -x + 7
D. y = x + 7

Answer 1

Find the slope
\[\LARGE \frac{y_2-y_1}{x_2-x_1}=slope\]

Answer 2

Does that make sense? :) take your two points
You have:
(2, 5) which is (x1,y1)
(4,3) which is (x2, y2)

Answer 3

The slope is not 2....try again.

Answer 4

c?

Answer 5

remember that your equation looks like this:
y=(slope)x+b
So if you take your points and do what pooja said than you will find at least your slope! :)

Answer 6

y = -x + 7?

Answer 7

That is correct

Answer 8

Mhm!! Exxcellent job.
