Answer: D

Step-by-step explanation:

The orange color is represented by the bottom line, which is y > x - 2

The purple color is represented by the top line, which is y < x + 1

How do we know the equations of those lines?

The equations can be written in the form y = mx + b where;
m = slope
b = y-intercept

The orange line:

crosses the y-axis at -2 --> b = -2
has a rise over run of 1 -> m = 1
--> y = x - 2
the line is dashed and is shaded above so y > x - 2

The purple line:

crosses the y-axis at +1 --> b = 1
has a rise over run of 1 -> m = 1
--> y = x + 1
the line is dashed and is shaded below so y < x + 1

the table shows the height of a plant as it grows. Which equation in point slope form gives the plants height at any time?

Answers

Answer:

y - 21 = 7(x - 3)

Step-by-step explanation:

If we plot the points on a graph having time on x axis and plant height on y axis then the two points will be (3, 21) and (5, 35).

Let the equation of the line is y - y'= m(x - x')

where m = slope of the line

Now slope of the line joining these points 'm' = $(y-y')/(x-x')$

m = $(35-21)/(5-3)$

m = $(14)/(2)$

m = 7

Now the equation that passes through the point (3, 21) will be y - 21 = 7(x - 3)

Therefore, equation that represents the height of the plant at any time is y - 21 = 7(x - 3)

(3,21)(5,35)
slope = (35 - 21) / (5 - 3) = 14/2 = 7

possible answers are :
y - 21 = 7(x - 3)
or
y - 35 = 7(x - 5)
or
y - 49 = 7(x - 7)
or
y - 63 = 7(x - 9)
