What is the slope of (6,5) and (4,7)

The slope is -1

Step-by-step explanation:

The equation for slope is given by

m = (y2-y1)/ (x2-x1)

Substituting in

m =(7-5)/(4-6)

   = 2/-2

m = -1

m = -1

Step-by-step explanation:

Here's what I consider to be the simplest approach to finding the slope:

As we move from (4,7) to (6,5), x increases by 2 and y decreases by 2.  Hence, the slope is m = rise / run = -2/2, or m = -1.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
