Question

find the slope of the line through the pair of points.
(6,-9) and (-3,5)

Answer 1

Use slope = delta y / delta x

Answer 2

Delta y = y2 - y1
Delta x = x2 - x1

Answer 3

\[slope= y2-y1 \div x2-x1 = 5--9\div -3-6\]= 14/-9=-1.56

Answer 4

@jesuskim m=[(-3)-(6)]/[(5)-(-9)] = -9/14

You did dx/dy :P

Answer 5

whoops my mistake. -14/9 is correct. I went and did dx/dy instead of dy/dx sorry!
thanks for finding it

Answer 6

the slope of the line is given by the equation:
slope(m) = rise/run = (dy/dx)

dy means change in the y values, and dx means the change in the x values.

so since the points are given in (x,y) fashion, you can set the equation up as follows:

m=[(5)-(-9)]/[(-3)-(6)] = -14/9

goodluck!
