The mum's age now = N
The daughter's age now = n
N=3n
N-6=6(n-6)
3n-6=6n-36
3n=30
n=10
The daughter's age now = 10
The mum's age now = 30

Write in point-slope form an equation of the line that passes through the given point and has the given slope. Point: (4, 8); m

Ainat [17]

Answer:

$\mathsf{y-8=\cfrac{3}{4}(x-4)}$

Step-by-step explanation:

Hi student, let me help you out!

<u>.. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. ... ... ..... ........ ...... ... ......... .... ....</u>

<u></u>

First, let's recall the point-slope form equation: ↪ $\mathrm{y-y_1=m(x-x_1)}$ .

<u>where: </u> y₁ = y-coordinate of the point (the second coordinate), m=slope, x₁=x-coordinate (the first coordinate).

Let's stick in the values accordingly. We obtain the following: $\mathrm{y-8=\cfrac{3}{4}(x-4)}$ , which is our point-slope form equation.

Hope this helped you out, ask in comments if any queries arise.

Best Wishes!
