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.

Please help me answer this question. First to answer will be marked braineist. NO WORK NESSACARY. Thank you ☺️

Lets check the first point (0,6)


3*0+4=4  no good

0+6 =6  good

0^2+6 =6 good

6 * (7/6) ^0 =6  good


Lets check the second point (1,7)

3*1+4=  we don't care since it didn't work for (0,6)

1+6 =7

1^2+6 =7

6 * (7/6) ^1 =7


Lets check the third point (2,10)


3x+4=  we still don't care

2+6 = 8 no good

2^2+6 =10  good

6 * (7/6) ^2 =6 * 49/36 =49/6  no good


f(x) = x^2 +6
