If A = (7,9) and B = (3 , 12) what is the length of AB

V125BC [204]

Answer:

AB = 5 units

Step-by-step explanation:

Calculate the length using the distance formula

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

with (x₁, y₁ ) = A(7, 9) and (x₂, y₂ ) = B(3, 12)

AB = $\sqrt{(3-7)^2+(12-9)^2}$

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

= $\sqrt{16+9}$

= $\sqrt{25}$

= 5

Point A(0, 8)

Point B(4, 5)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

Substitute in points [Slope Formula]: $\displaystyle m=\frac{5-8}{4-0}$
[Fraction] Subtract: $\displaystyle m=\frac{-3}{4}$
