Question

What is the slope of the line that passes through the points (3, 1) and (–2, 5)?

A.
-5/4

B.
-4/5

C.
5/4

D.
4/5

I got A is that right?

Answer 1

Not correct. Slope is \[m=\frac{rise}{run}=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}\]

Answer 2

You have your x's and y's switched.

Answer 3

oh, so if I switched them, would it make it 5/4?

Answer 4

slope(m) = (y2 - y1) / (x2 - x1)
(3,1) x1 = 3 and y1 = 1
(-2,5) x2 = -2 and y2 = 5
now sub
slope(m) = (5 - 1) / (-2-3)
slope(m) = 4/-5
slope -4/5

do you understand ?

Answer 5

Yes, Thank you for explaining it :)

Answer 6

sure thing...glad to help :)
