Question

A,B,C or D????????

I need helpp

Answer 1

B

Explanation:

To calculate the slope or gradient of line use the formula:

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

Thus, the slope of this line

`= (9 - 10)/(9 - 2) = ( - 1)/(7)`

Thus, the answer is B

Answer 2

B

Explanation:

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

y2 = 10

y1 = 9

x2 = 2

x1 = 9

Which point you call 2 and which you call 1 does not matter. You will get the same answer. Once chosen, you must be consistent.

slope = (10 - 9) / (2 - 9)

slope = 1 / -7
