Question

Find the slope of the line that passes through the points (1,4) and (4,7).
a.-3/2
b. 1
c. 3/2
d. 2

Answer 1

What are the y coordinates for the points given?

Answer 2

this is the only information given to me on this problem

Answer 3

If I gave you the point (2,3), what is the y coordinate of this point?

Answer 4

oh sorry lol its 4 and 7....right?

Answer 5

you got it

Answer 6

Subtract the first from the second, so..


Second - First = 7 - 4 = 3

Answer 7

Do the same (in the same order) for the x coordinates

Answer 8

4-1=3

Answer 9

so the slope is...


Slope = (y difference)/(x difference)

Slope = 3/3

Slope = 1

Answer 10

It's coincidental in this case that the two differences are the same, usually they aren't

Answer 11

okay thanks!:)

Answer 12

sure thing
