Question
Two different points on a number line are both 3 units from the point with coordinate -4. The solution to which of the following equations gives the coordinates of both points?
Hint:
Hint:
- The distance between two point a:b on number line will be
The correct answer is:
Explanation:
- We have given two different points on number line and both are 3 units from the point with coordinate -4.
- We have find the equation whose solution gives us the coordinate of both points.
Step 1 of 1s:
Let the coordinate of point be x.
Now we know that, the distance between two point a:b on number line will be
So, The distance between the given point with coordinate -4 and the point with coordinate x will be
And it is given that this distance is equal to 3 units.
So,
= 3
So, Option (A) is correct.

In sets of numbers called fractions, the top number (numerator) represents a portion related to the entire unit, and (the denominator) by the bottom number.
A ratio is similar to a fraction, where two numbers are compared. Although ratios can be written in fractional form, they are typically expressed as numbers separated by the colon symbol.
The ratio conversion into a fraction in mathematics is known as the ratio to a fraction. The ratio conveys the relative size of two or more values. The fraction similarly identifies the components of the whole. A: B or a/B are two ways to represent the ratio.
