Point A(1,9) and point B(−4,−3) are located within the coordinate plane.

AlekseyPX

Answer:

The answer to your question is 13 units

Step-by-step explanation:

Data

A (1, 9)

B (-4, -3)

distance = ?

Formula

distance = $\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}$

Substitution

distance = $\sqrt{(-4 - 1)^{2} + (-3 - 9)^{2}}$

Simplification

distance = $\sqrt{(-5)^{2} + (-12)^{2}}$

distance = $\sqrt{25 + 144}$

distance = $\sqrt{169}$

Result

distance = 13

-4y>2x+4 What is the slope of this

vovikov84 [41]

Answer: -1/2

Explanation: -4y > 2x + 4; isolate the y by dividing both sides by -4 and get:
y = -2/4x + 4; simplify
y = -1/2x + 4

In y = mx + b; m is the slope

In this case, -1/2 is the slope
