WRITE AN EQUATION THAT REPRESENTS THE LINE. (USE EXACT NUMBERS) <br> I WILL GIVE BRAINLIEST!!!

xxMikexx [17]

Answer:

y = -1/2x - 3 1/2 exact fractions

y = -0.5x - 3.5 exact decimals

Step-by-step explanation:

From the two points indicated on the graph

rise goes from -4 to -5 = -1

run goes from 1 to 3 = 2

m = slope = rise/run = -1/2

slope intercept form is

y = mx+b

to find "b" use either point

using (1, -4)

-4 = (-1/2)(1) + b

-4 = -1/2 + b

Add 1/2 to both sides

-3 1/2 = b

The equation is

y = -1/2x - 3 1/2 exact fractions

y = -0.5x - 3.5 exact decimals

Write a rule for g described by the transformation of the graph of f...

Svetlanka [38]

Answer:

$g(x) = 4-4\sqrt{x}$

Step-by-step explanation:

Given

$f(x) = 4\sqrt{x}+1$

1. 5 units down translation

2. Reflection in the x-axis

Required

Determine the resulting function g

1. 5 units down translation

This is defined by the rule:

A down translation is:

$f'(x) = f(x) - b$

Where b is the number of units.

So, we have:

$f'(x) = 4\sqrt{x} + 1 - 5$

$f'(x) = 4\sqrt{x} -4$

2. Reflection in the x-axis

For a function f(x),

When reflected over the x-axis, it becomes -f(x)

So:

$g(x) = -f(x)$

$g(x) = -(4\sqrt{x} - 4)$

$g(x) = -4\sqrt{x} +4$

$g(x) = 4-4\sqrt{x}$

I believe it is 15 if the model is drawn to scale, this is because x and the other ray of 15 are both connected to the vertex P and extend to the edges
