What does this graph tell you about the growth of the Corn stock

ladessa [460]

The question is very vague, but here's what it tells me.
We know that the coordinates are (4, 25) meaning the x is 4 and the y is 25.
Since time is x and height is y, all this is saying is this:
After 4 weeks, the corn stock is 25 inches.

You can go deeper and divide 25 by 4 to find out the rate of growth. That would give you 6.25, meaning
The corn stock grows 6.25 inches every week.

What is the line that passes through points 6,9 and 11,2

Zepler [3.9K]

The final equation of line passing through (6,9) and (11,2)

$y=-\frac{7}{5}x+\frac{87}{5}$

Further explanation:

The general form of equation is:

$y=mx+b$

We have to find the slope first

$m=\frac{y_2-y_1}{x_2-x_1}\\Here\\(x_1,y_1)=(6,9)\\(x_2,y_2)=(11,2)\\Putting\ the\ values\\m=\frac{2-9}{11-6}\\=-\frac{7}{5}$

Putting the value of m in general form

$y=-\frac{7}{5}x+b$

For finding the value of b, putting (6,9) in equation

$9=-\frac{7}{5}(6)+b\\9=-\frac{42}{5}+b\\9+\frac{42}{5}=b\\b=\frac{45+42}{5}\\$

$b=\frac{87}{5}$

Putting the values of b and m

The final equation of line passing through (6,9) and (11,2)

$y=-\frac{7}{5}x+\frac{87}{5}$

Given f(×) and g(×) = f(kx), use the graph to determine the value of k

Vitek1552 [10]

The value of k is 3

Solution:

Let us first find the equation of the line f(x).

The points on the line are (-6, -2) and (0, 4).

Here, $x_1=-6, y_1=-2, x_2=0, y_2=4$

Formula to find equation of a line:

$$\frac{y-y_1}{x-x_1} =\frac{y_2-y_1}{x_2-x_1}$

$$\frac{y-(-2)}{x-(-6)} =\frac{4-(-2)}{0-(-6)}$

$$\frac{y+2}{x+6} =\frac{4+2}{6}$

$$\frac{y+2}{x+6} =\frac{1}{1}$

Do cross multiplication.

y + 2 = x + 6

y = x + 4

f(x) = x + 4

Given that g(x) = f(kx)

g(x) = kx + 4

The point in the graph of g(x) is ( -2, -2).

g(-2) = k(-2) + 4

we know that g(-2) = -2.

-2 = -2k + 4

Subtract 4 from both sides.

-6 = -2k

Divide by -2 on both sides.

3 = k

k = 3

The value of k is 3.
