Question

Someone please help me with some of these math problems.I need good geometry student​

Answer 1

plug in the x and y coordinates! the equation in green shows you what you need. a=(-3,1) b=(-1,-1)

2.8

Explanation:

Answer 2

d = 2√2

Explanation:

A ( -3,1) ; B(-1,-1)

d² = (x₂-x₁)² + (y₂ - y₁)²

= (-1- [-3] ) ² + (-1 - 1)²

= (-1 + 3)² + (-1-1)²

= 2² + (-2)²

= 4 + 4

= 8 = 2 * 2 *2

d =√ 2 * 2*2 = 2√2
