Select the three equations that pass through the points (-4, -16) and (5,2).
dezoksy [38]

Answer:

The equation of the line is y-2 = 2(x - 5), that passes through points (-4, -16)\ and\ (5,2)

Step-by-step explanation:

Given points are (-4, -16)\ and\ (5,2)

We need to write the equation of the line that passes through these points

First, we will find slope of this line

m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-(-16)}{5-(-4)}\\\\m=\frac{2+16}{5+4}\\\\m=\frac{18}{9}=2

So, our slope is 2. Now, we will plug the point (5,2) in the equation below.

(y-y_1)=m(x-x_1)\\y-2=2(x-5)\\

So, the equation of the line is y-2 = 2(x - 5).

Which transformations are needed to change the parent some function to the sine function below?
Marrrta [24]
Beginning with the function y = sin x, which would have range from -1 to 1 and period of 2pi:
Vertical compression of 1/2 compresses the range from -1/2 to 1/2
Phase shift of pi/2 to the left
Horizontal stretch to a period of 4pi, as the crests are at -4pi, 0, 4pi
Vertical shift of 1 unit up moves the range to 1/2 to 3/2
So the first choice looks like a good answer.
