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!

almond37 [142]

In order for the curve to move upwards from left to right as shown the log and x values need to be negatives. The curved line crosses the x axis to the right of the origin, so there needs to be a positive value added to x.

The answer is d. F(x) = -4log(-x+4)
