Question

Find the slope of the line through each pair of points. (9.-14). (8-8)​

Answer 1

`\boxed {\tt m= -6}`

Explanation:

The slope formula is:

`m=(y_2-y_1)/(x_2-x_1)`

where (x₁, y₁) and (x₂, y₂) are the points given.

The points are (9, -14) and (8,-8). Therefore,

x₁=9

y₁= -14

x₂= 8

y₂= -8

Substitute the values into the formula.

`m=(-8 - -14)/(8-9)`

`m=(-8 +14)/(8-9)`

Solve the numerator.

`m=(6)/(8-9)`

Solve the denominator.

`m=(6)/(-1)`

Divide 6 by -1.

`m= -6`

The slope is equal to -6

Answer 2

-6

Explanation:

We can use the slope formula

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

= ( -8- -14)/( 8 -9)

= ( -8+14)/( 8 -9)

6/-1

-6
