Question

the points in the table lie on a line. find the slope of the line (X. -2, -1, 0, 1) (Y. -10, -6, -2, 2)​

Answer 1

Answer: the slope of the line is 4

Explanation:

We only need two ordered pairs to find the slope

(-2,-10), (-1,-6)

the slope formula is y2-y1/x2-x1

-6-(-10)/-1-(-2)

-6+10/-1+2

4/1

4

the slope of the line is 4

Answer 2

4

Explanation:

Knowledge Needed

The slope is the amount the y-value changes on a line when the x-value changes by 1.

Slope Formula:
`(y_2-y_1)/(x_2-x_1)`

Question:

We have the points:

(-2,-10)

(-1,-6)

(0,-2)

(1,2)

We only need 2 points to plug into the slope formula. I'll use the first 2.

(-2,-10) ; (-1,-6)

`(-6--10)/(-1--2)`

`(4)/(1)`
