Find the distance between the points (-1,-9) and (1,-4)
Snezhnost [94]

The distance between the two points is 5.4

Explanation:

The points are (-1,-9) and (1,-4)

The distance between the two points can be determined using the formula

d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}

Substituting the values in the formula, we get,

d=\sqrt{(1+1)^{2}+(-4+9)^{2}}

Adding the values,

d=\sqrt{2^{2}+5^{2}}

Squaring the terms, we get,

d=\sqrt{4+25}

Simplifying, we have,

d=\sqrt{29}=5.4

Thus, the distance between the two points is 5.4
