Select the correct answer. Which equation represents this line in point-slope form? A. `(y + 4) = (4)/(3) (x + 3)` B. `(y −4) =
Readme [11.4K]

Answer:

The correct option is `(y −4) = -(4)/(3) (x +3) ..

Step-by-step explanation:

Look at the attached picture:

The points we have given are (-3, 4) and (3, -4)

Find the slope by applying the formula:

m = y2-y1/x2-x1

Here x1= -3

x2= 3

y1 = 4

y2 = -4

Now put the values in the formula:

m = -4 -4 /3 -(-3)

m = -8/3+3

m = -8/6

Now cancel the term by table of 2

m = -4/3

When two points are given, the equation of the line is

(y - y1) = m (x - x1)

y - 4 = -4/3 (x - (-3))

y-4 =  -4/3 (x+3)

Thus the correct option is `(y −4) = -(4)/(3) (x +3) ....

Please help or I am going to fail <br> what do I graph I don't know what I am doing

Y=-1/5x+3 the 3 would be the y intercept and the -1/5 is your slope and you would start at the 3 and use your slope and go down one and over five since it’s negative

Mary measured the heights of two different plants every day. Plant A was 1 inch tall when
seropon [69]

The heights of plant A and plant B will be equal on the day 8.

<h3>How to find the heights of the trees?</h3>

The height of the tree can be found as follows:

The equation for plant A can be described as follows:

y = 1 + 0.5x

where

x = number of days

y = height

The equation for plant B can be described as follows:

y = 3 + 0.25x

Therefore, for the height to be equal

1 + 0.5x =  3 + 0.25x

1 - 3 = 0.25x  - 0.5x

-2 = -0.25x

x = 2 / 0.25

x = 8 days
