Question

Help me with 8 pls
-5 10
-3 6
-1 2

Answer 1

a) -2

b) 1/2

Explanation:

To find the slope given 2 points use the formula:

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

Use the 2 points:

(-5,10)

(-3,6)

`(6-10)/(-3+5)\\ (-4)/(2) \\-2`

So, a has a slope of -2.

Given the 2 points on the graph:

(-1,4)

(-5,2)

use the same formula:

`(2-4)/(-5+1)\\ (-2)/(-4)\\ 1/2`

so b has a slope of 1/2

Hope this helps! :)

Answer 2

12

Explanation:

Select any two random points on the graph of the line (preferably with integer coordinates).

Label them as A and B (in any order).

Calculate the "rise" from A to B. While going vertically from A to B, if we have to go. ...

Calculate the "run" from A to B. ...

Now, use the formula: slope = rise/run.
