Answer:

449/198 or 2 53/198

Step-by-step explanation:

2. 2676767 = x

10x= 22. 67676767

1000x= 2267. 676767

1000x-10x= 2267.676767- 22.67676767

990x= 2245
x= 2245/990
x= 449*5/5*198
x= 449/198
x= 2 53/198

What is the equation in point-slope form of the line passing through (−2, 0) and (2, 8)? (1 point) y = 2(x + 2) y = 2(x − 2) y =

Sonja [21]

Answer: $y=2(x+2)$

Step-by-step explanation:

The slope of the line is

$y=\frac{8-0}{2-(-2)}=\frac{8}{4}=2$

Using the point (-2, 0) to substitute into point-slope form, we get the equation to be $\boxed{y=2(x+2)}$
