A line that includes the points (0,w) and (–1,2) has a slope of 6. What is the value of w?
mars1129 [50]

Answer:

8

Step-by-step explanation:

slope =  \frac{w - 2}{0 - ( - 1)}  \\  \\  \therefore \: 6 =  \frac{w - 2}{0 + 1} \\  \\  \therefore \: 6 =  \frac{w - 2}{1}  \\  \\ \therefore \:w - 2 = 6 \\  \\  \therefore \:w = 6 + 2 \\  \\  \therefore \:w = 8\\  \\

10 2/6 - 7 5/6 i know its prob easy but i need help
miv72 [106K]

Answer: 2 1/3

Explanation:

10 2/6 - 7 5/6

You can make both a fraction by multiplying the denominator by the whole number, and then adding the numerator to that number, and keeping the denominator the same. So, 10*6 = 60 and 60 + 2 = 62 and you keep the denominator as 6, which would make 62/6

7*6 = 42 and 42 + 5 = 47 so 7 5/6 becomes 47/6

10 2/6 is equivalent to 62/6

7 5/6 is equivalent to 47/6

This just makes it easier to look at.

Now you just work through the equation.

62/6 - 47/6 = 15/6

15/6 = 2 3/6 = 2 1/3
