Which equation represents the linear function that is shown on the graph below?

d1i1m1o1n [39]

Answer:

$y = \frac{1}{2}x - 2$

Step-by-step explanation:

Given

The attached graph

Required

Determine the linear equation

First, we need to calculate the slope

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

From the graph, the following relationships exist:

$(x_1,y_1) = (4,0)$

$(x_2,y_2) = (10,3)$

So, the expression for calculating slope becomes:

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

$m = \frac{3-0}{10-4}$

$m = \frac{3}{6}$

$m = \frac{1}{2}$

Next, we calculate the equation using:

$y - y_2 = m(x - x_2)$

This gives:

$y - 3 = \frac{1}{2}(x - 10)$

Open bracket

$y - 3 = \frac{1}{2}x - 5$

Make y the subject:

$y = \frac{1}{2}x - 5+3$

$y = \frac{1}{2}x - 2$

For the quadratic function below, what is the rate of change over the interval.

Darya [45]

Answer:

Step-by-step explanation:

Intervals are always x values. When x = 5, y = 4 (look at the graph to se this); when x = 6, y = 2. The rate of change is the same thing as the slope. We can't get an exact slope here because this isn't a straight line, but we can find the average rate of change. We use the slope formula to do this: with the coordinates (5, 4) and (6, 2):

$m=\frac{2-4}{6-5}=\frac{-2}{1}=-2$ . Third choice down is the one you want.

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

Your answers are:

Step-by-step explanation:

A) 0.5

B) 1/2

How do we get from a decimal to a percent? We multiply by 100. So 0.5 * 100 = 50%. A) is correct.

How do we go from a fraction to a percent? Percent means "out of 100" so a fraction out of 100 is how you can tell if the percent matches the fraction.

1/2 = ?/100

1/2 = 50/100

Half of 100 is 50, so B) is correct.

To save the explanation, C) and D) are incorrect because C) ends up being 5% while D) ends up being 2%.

Your answer is A) and B).

I hope this helps!
