Answer:

Step-by-step explanation:

To get the length of segment HJ if H lies at (-1,7) and J lies at (8,-5), we will use the formula for calculating the distance between two points as shown;

D = √(x₂-x₁)²+(y₂-y₁)²

From the coordinates x₁ = -1, y₁ = 7, x₂ = 8, y₂ = -5

HJ = √(8-(-1))²+(-5-7)²

HJ = √(8+1)²+(-12)²

HJ = √81+144

HJ = √225

HJ = 15

<em>Hence the length of segment HJ is 15 units</em>

Answer:

≈ 3.16 units

Step-by-step explanation:

To determine the distance between the two points, we need to use the distance formula. The distance formula states that;

$\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$

Given coordinates;

(6, -5)
(5, -8)

When we substitute the coordinates into the formula, we get;

$\implies \sqrt{[5 - 6]^{2} + [-8 - (-5)]^{2} }$

When we simplify the root, we get;

$\implies \sqrt{[-1]^{2} + [-8 + 5]^{2} }$
$\implies \sqrt{[-1]^{2} + [-3]^{2} }$
$\implies \sqrt{1 +9 }$
$\implies \sqrt{10}$ units ≈ 3.16 units (Using calculator)

Therefore, the distance between the points is about 3.16 units.
