Question

I need a proper answer please, thanks so much.

Answer 1

Start of by setting up the slope formula: 
$\frac{y_2-y_1}{x_2-x_1} =slope$

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
$\frac{4-w}{-10-(-6)} = \frac{1}{8}$


Simplify the current info given: 
$\frac{4-w}{-4} = \frac{1}{8}$

Now you would be able to guess and check, 

Final answer: w=9/2
