Answer:

y=2x-3

Explanation:

which equation represents the relationship between x and y shown in the table?

x | y

2 | 1

4 | 5

6 | 9

8 | 13

take a look at the values in the table one more,

we find the gradient of the line to be

G=y2-y1/(x2-x1)

G=13-1/(8-2)

slope/gradient=12/6

m=2

from equation of a line graph, we know

y=mx+c

m=gradient

c=intercept

y=vertical axis

x=a point on the horizontal axis

y=2x+c

when x=6, y=9

9=2(6)+C

c=-3

Therefore the equation becomes

y=2x-3

Which fraction represents the decimal 0.8888...?

suter [353]

Answer: The decimal 0.88888.... represented by the fraction $\dfrac{8}{9}$

Step-by-step explanation:

Since we have given that

0.888888....

So, Let x = 0.88888....= $0.\bar{8}$ -----(1)

Now, multiply by 10 on both sides, we get that

$10x=8.8888.....=8.\bar{8}----------(2)$

Now, Subtracting (1) from (2), we get that

$10x-x=8.\bar{8}-0.\bar{8}\\\\9x=8\\\\x=\dfrac{8}{9}$

Hence, the decimal 0.88888.... represented by the fraction $\dfrac{8}{9}$
