Question

Can anybody help with some questions.

2.
The slope of the line that passes through the points (-6,w) and (-10,4) is 1/8 what is the value of w?
F. 36
G. 34
H. 9/2
J. 1/2

Answer 1

You can use the slope formula to find the missing variable.

`m = (y_(2)-y_(1))/(x_(2)-x_(1))`

And plug in what you know into the equation.

`m = (y_(2)-y_(1))/(x_(2)-x_(1))`

`(1)/(8)=  (4-w)/(-10+6)`

`(1)/(8)= (4-w)/(-4)` Multiply -4 on both sides

`(-4)/(8)=4-w` Simplify -4/8, then subtract 4 on both sides

`(-1)/(2) - 4 = -w` Make the denominators the same

`(-1)/(2) -  (8)/(2) = -w`

`(-9)/(2)=-w` Multiply -1 on both sides

`(9)/(2) =w`

Your answer is H
