Question

Plsss help final test working out needed

Answer 1

Answer:

1) Length = 5.7

2) Midpoint = (0, 2)

3) Gradient = 1

Step-by-step explanation:

We are given the intervals as;

A(-2, -1) and B(2, 3)

1) Formula for length of interval is;

AB = √[(3 - (-1))² + (2 - (-2))²)]

AB = √(16 + 16)

AB = √32

AB = 5.66 ≈ 5.7

2) Midpoint of the interval is;

((-2 + 2)/2), (-1 + 3)/2

This gives; (0, 2)

3) gradient is the slope and it's given by;

m = (y2 - y1)/(x2 - x1)

m = (3 - (-1))/(2 - (-2))

m = 4/4

m = 1
