What is the slope of the line that contains these points?<br> (-1,10) (0,18) (1,26) (2,34)

-BARSIC- [3]

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

The formula of the slope is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$(x_{1},y_{1})$ and $(x_{2},y_{2})$ are 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

∴ $x_{1}$ = 0 and $x_{2}$ = 1

∴ $y_{1}$ = 18 and $y_{2}$ = 26

- Substitute these values in the formula of the slope above

∵ $m=\frac{26-18}{1-0}$

∴ $m=\frac{8}{1}$

∴ m = 8

The slope of the line that contains these points (-1 , 10) , (0 , 18) , (1 , 26) , (2 , 34) is 8

If You know how to do long division then... You move the decimal that’s outside the house to where it’s not there no more then divide . Or turn the decimals into Fractions and do the reciprocal.
