Question

Describe a method other than the one used in the example that you
could use to find a.

Answer 1

Answer: d ≈ 8.9 units

Explanation:

We will use the distance formula. Let point S be the first point, and point R be the second. We will plug in the values and solve.

`\displaystyle d=\sqrt{(x_(2)-x_(1))^2 +(y_(2)-y_(1))^2}`

`\displaystyle d=√(3--5)^2 +(1-5)^2)`

`\displaystyle d=√((8)^2 +(-4)^2)`

`\displaystyle d=√(64 +16)`

`\displaystyle d=√(80)`

d ≈ 8.9 units
