x is a positive integer. If the rightmost digit of x is moved to the leftmost position (for example 1234 would become 4123), the new integer is exactly 2x. As you might expect, there are an infinite number of integers with this property. What is the smallest one?

Then use the point-slope form of the equation to write the slope-intercept form. Passing through (3, 4) and (2, 1).

I am having a hard time, still, doing the equation to find the point slope form. What can I do to make this understanable?

I've heard that smog and pollution are keeping us from seeing the light the stars are shining to us. How can we help prevent pollution and smog so everyone could watch the stars at night?

Is Earth, the moon, and all other planets, made of similar texture and material, or are they different? Are some different, while others are similar?

If a star explodes (a star can explode, right?), then after a long period of time, the light seizes to shine, correct? What happens to a star after it explodes?

What is the longest it could take for the light of a star to be visible with the naked eye? (It does take a very long time for starlight to reach us from where the star is, right?)
