Answer:

(0,2)

Step-by-step explanation:

Convert the equation to <em>y=mx+b</em>.

You get y=1/2+2.

Since x is always 0 in your y-intercept and the y value is equal to <em>b, </em>you get (0,2) as your coordinate pair.

Answer:

(0,2)

Step-by-step explanation:

Given equation is :

2x-4y=-8

y=mx+b is slope-intercept form of equation of a line where m denotes slope and b denotes y-intercept.

We have to transform given equation into slope intercept form.

2x-4y=-8

Adding -2x to both sides of above equation,we get

-2x+2x-4y=-2x-8

0-4y=-2x-8

-4y=-2x-8

Dividing by -4 to both sides of above equation,we get

-4y / -4=(-2x-8) / -4

y= 1/2x+2 is slope intercept form of given equation  where slope is 1/2 and y-intercept  is 2.

y-intercept is a point where x is zero.

Hence ,(0,2) represents the y-intercept of given equation.

What is the average of the four smallest of integers ?
Elanso [62]
This question is easier than it seems. If there are 9 consecutive integers with the mean being 16, then 16 must be the median. So just add four on top and four below 16 to give you your range of 9 values, 12-20. 12+13+14+15+16+17+18+19+20=144, 144/9=16. So the mean of the first four numbers is (12+13+14+15)/4= 13.5. If you check, 13.5 is also the median of these four numbers.

Solve (x+y) if x=-1/2 and y=-3
bixtya [17]

Answer:

-3\frac{1}{2}

Step-by-step explanation:

Solve

(x+y)

For x=-1/2 and y=-3

substitute the value of x and the value of y in the expression above

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

Remember that

(+1)(-1)=-1

so

x+y=-\frac{1}{2}-3=\frac{-1-6}{2}=-\frac{7}{2}

Convert to mixed number

-\frac{7}{2}=-\frac{6}{2}-\frac{1}{2}=-3\frac{1}{2}
