I need a proper answer please, thanks so much.


The slope of the line that passes through the points (-6, w) and (-10, 4) is 1/8. What is the value for w?
A) 36
B) 34
C) 9/2
D) 1/2

Respuesta :

Start of by setting up the slope formula: 
[tex] \frac{y_2-y_1}{x_2-x_1} =slope[/tex]

We are given 2 coordinates and the slope
(-6,w)(-10,4) 
slope:1/8 

Label your coordinates: 
(-6,w) and (-10,4) 
 x1,y1         x2-y2

Put these numbers into the formula
[tex] \frac{4-w}{-10-(-6)} = \frac{1}{8}[/tex]


Simplify the current info given: 
[tex] \frac{4-w}{-4} = \frac{1}{8}[/tex]

Now you would be able to guess and check, 

Final answer: w=9/2
