Answer:
<em>Option B, Option D</em>
Step-by-step explanation:
If we are to take a look at these points, we would see that they share a common y point on the y - axis ⇒ -5;
This would mean that a horizontal line runs through the following points ( 4, -5 ) and ( 6, - 5 ), and provided it is a horizontal line, it has no slope, or in other words a slope of 0;
<em>Solution; Option B, Option D</em>
The first digit of a number can be 1-9. The 2nd and the 3rd digit can be 1-10. The last digit can be 0 or 5 ( 2 numbers ):
9 * 10 * 10 * 2 = 1,800
She could pick 1,800 different 4-digit numbers.
Rounding 218 ⇒ 220.
Hoped this helped.
