Based on the graph, which equation represents the relationship between the height of trees (y) and the amount of rainfall (x)?

slega [8]

Given:

Given that the graph that shows the amount of rainfall( in centimeters) and the height of the trees( in meters)

We need to determine the equation that represents the relationship between the height of trees(y) and the amount of rainfall(x).

Slope of the equation:

The slope can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the points (20,10) and (40, 20) in the above formula.

Thus, we get;

$m=\frac{20-10}{40-20}$

$m=\frac{10}{20}$

$m=0.5$

Thus, the slope of the equation is 0.5

y - intercept:

The y - intercept of the equation is the value of y when x = 0.

Thus, from the graph, when x = 0, the value of y is 0.

Hence, the y - intercept is b = 0

Equation of the graph:

The equation of the given graph can be determined using the formula,

$y=mx+b$

Substituting the values, we get;

$y=0.5x+0$

$y=0.5x$

Thus, the equation that represents the relationship between the height of the trees (y) and the amount of rainfall (x) is $y=0.5x$

Hence, Option C is the correct answer.

Answer:

y = 1/3*x -3

Step-by-step explanation:

Method 1:

Grab two random points from the line.

(0,-3) and (3,-2)

Using the Point-Slope Form solve for m.

(-3 - (-2)) = m * (0 - (3))

-1 = m * (-3)

m = 1/3

Turning Point-Slope form into Slope intercept Form.

(y - (-3)) = 1/3 * (x - 0)

y + 3 = 1/3x

y = 1/3 - 3

Method 2:

Look at the y-intercept since y-int becomes our b. b = -3

From the y-int count rise/run as thats our Slope m. m = 1/3

Slope-intecept Form:

y = 1/3*x -3

What equation can be used to show that the slope of the line is the same between any two points?

Blizzard [7]

If you think about slopes it will always be rise over run! Think of rise as climbing a mountain and run as in walking on the mountain you just climbed. In order to find an equation of any problem, you first need to look at a graph for your first clue. See if the line goes straight through the corners of certain places on the graph. If so than you just count rise over run!
In conclusion my thesis or solution for your question would be C.

Answer:

Equation: (650 + 20) < (450 + 25)
Sentence to answer with: Cardinal Gold Club is the better golf couse because it is cheaper when we compare to total of both prices altogether.

Step-by-step explanation:

The reason why this club is better is because in Red Crest the fee is 650 and the charges per round is 20 so we add 650 + 20 to get the total of 670. Now we have to find the total of the Cardinal Golf Club and to do that we have to add their fee of 450 + the charges for each round which is 25 and 450 + 25 equals to 475. Lastly we have to compare to find the less/cheaper one ehich is Cardinal.
