Question

Find the distance between the points (0,-9) and(4,-6)

Answer 1

Answer:

d=5

Step-by-step explanation:

1. use the distance formula: d=$\sqrt{(x_{2} - x_{2} )^{2} +(y_{2} -y_{1} )^{2}$

2. plug in the points: d=$\sqrt{(0-4)^{2} +(-9+6)^{2}$

3. solve problem inside parentheses: d=$\sqrt{(-4)^{2} +(-3)^{2}$

4. square -4 and -3: d=$\sqrt{16+9$

5. add:d=$\sqrt{25$

6. find square root: d=5
