Answer:
y = 4x
Step-by-step explanation:
You can take 2 points on the line, then find the slope from that using (y2-y1)/(x2-x1). From there, use point slope form to get y - 4 = slope (x -1). Simplify this and you get y =4x.

For rounding, if the place one more to the right of the place you are rounding is 0-4, you go down. If it is 5-9, then round up. For the first one, you are rounding to hundreds, so look at the tens. It ends on a 5, so round up. Making the number 700. For the second one, look at the tens again, and you see it is more than 5, so it is 800. The last one is tricky, but do-able. Look at the hundreds. It’s a four. So that means you keep the same number, making it 6,000. I hope this helps!
