What is the slope of the line that passes through the points (10,6) and (9,5)

Here, we will use the slope formula.

Slope formula can be read as the second y minus the

first y over the second x minus the first x.

So for this problem, the second y minus the first y would be 5 - 6

and the second x minus the first x would be 9 - 10.

5 - 6 over 9 - 10 simplifies to -1/-1 which reduces to 1.

Always remember to reduce if possible as your last step.

the answer is d
