What is the distance between point a (−1, 3) and point b (−7, 3) ? 1 units 3 units 6 units 8 units

The distance between point A and the point B is:

6 Units.

Step-by-step explanation:

The Cartesian plane is known as 2 perpendicular number lines between them, one horizontal and one vertical, which are cut at a point called the origin.

And the coordinates are given by the values of X and Y (x, y)

Where X are horizontal values and Y are vertical values.

By placing the point (−1, 3) and the point (−7, 3) we realize that two values of Y are exactly the same on the line.

But the values of X are different from each other, so the units of the distance between them are counted.

-7U - (- 1U) = -6U

But since the distance units cannot be negative then the answer is 6 units of distance.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
