Answer:
w = 9
Explanation:
Use a slope formula to solve. Subtract the y's put that on top and subtract x's and put that on the bottom. This calc should equal 2 that was given.
(8-6)/(10-w) = 2
2/(10-w) = 2
Cross-multiply.
2 = 2(10-w)
Distributive property
2 = 20 - 2w
Add 2w
2 + 2w = 20
Subtract 2
2w = 18
divide by 2
w = 18/2 = 9
Or you can logic it out...8-6 is 2 on top. Need a 1 on the bottom (bc 2/1 is 2) 10-9 is 1 for on the bottom. w = 1
