What is the slope of the line with the equation y-3=-1/2(x-2)?
torisob [31]

Answer:  -\frac{1}{2}

Step-by-step explanation:

y -3 = -\frac{1}{2}(x-2)

Write as slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

y-3=-\frac{1}{2}x + 1

     y = -\frac{1}{2}x+4

Therefore, the slope is -\frac{1}{2}.

What is 1 out of 7 + 1/2 plz help
scoray [572]
Answer: 9/14

Explanation. First, you have to find the least common denominator. The least common denominator is the lowest number you can use on the denominator to create a set of equivalent fractions

7 and 2 can both go into 14
Whatever number you use to multiply to equal 14, you do the same to the top.
It would look like this.

2/14 + 7/14
Then you add.

2/14 + 7/14= 9/14
You can’t simplify this fraction so this is your answer. Hope this helped!
