Answer:
Step-by-step explanation:
The first thing you must remember is the mulplication of signs. You know that:
You can observe that the number inside the parentheses is positive (+) and the sign that is outside the parentheses is negative (-), therefore, when you multiply these signs you get a negative sign (-). Then you get:
Now, you need to add these numbers. And the result obtained is:
The slope of the line that contains these points (-1 , 10) , (0 , 18) , (1 , 26) ,
(2 , 34) is 8
Step-by-step explanation:
You can find the slope of a line from any two points lie on it
∵ A line contains these points (-1 , 10) , (0 , 18) , (1 , 26) , (2 , 34)
- To find the slope of the line chose any to points
∵ Points (0 , 18) and (1 , 26) lie on the line
∴ = 0 and
= 1
∴ = 18 and
= 26
- Substitute these values in the formula of the slope above
∵
∴
∴ m = 8
The slope of the line that contains these points (-1 , 10) , (0 , 18) , (1 , 26) , (2 , 34) is 8
