10
The slope of the line is
a.5
b. -2
c. 6
d. -3

Answer 1

slope would be -2

Explanation:

slope formula

`\frac{ {y}^(2) - {y}^(1) }{ {x}^(2) - {x}^(1) }`

We know: (1, 9) and (4, 3)

plug in the numbers

`(9 - 3)/(1 - 4)`

subtract

`(6)/( - 3)`

divide

`- 2`

Tadaaaa

Answer 2

The answer is b.) -2
