Answer:

The equation of the line is y = 1/5x + 18/5, which means the intercept is 18/5.

Step-by-step explanation:

In order to find this, we need to start by finding the slope. To do that, we need to use the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (5 - 3)/(7 - -3)

m = (5 - 3)/(7 + 3)

m = 2/10

m = 1/5

Now that we have the slope, we can use either point and the slope in slope intercept form to find the intercept.

y = mx + b

3 = 1/5(-3) + b

3 = -3/5 + b

18/5 = b

Answer:

y = 0.2x + 3.6

Step-by-step explanation:

3 + 7 = 10

2 / 10 = 0.2

y = 0.2x + ___

0 - (-3) = 3

3 * 0.2 = 0.6

3 + 0.6 = 3.6

y = 0.2x + 3.6

Answer:

(3x+5y)/8

Step-by-step explanation:

The total amount is 150+250=400

We then do (3x+5y)/2 × 1/400

This equals (3x+5y)/800

We multiply that by 100 giving us the final answer.

Answer:

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}

The relation is a function.

Step-by-step explanation:

A relation is any set of ordered pairs, which can be thought of as (input, output).

A function is a relation in which no two ordered pairs have the same first component and different second components.

Remember that a function can only take on one output for each input. We cannot plug in a value and get out two values.

The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

I did the Vertical Line Test on your given graph. As you can see from the attached screenshot, each vertical line crosses the graph only once. Therefore, the given relation is a function.

The domain of the given relation is the set of x-values, while the range is the set of y-values. You'll have to list the ordered pairs in order to determine the domain and range of the given relation.

Relation: {(-4, -1), (-2, 1), (1, -2), (2, 4), (4, -4)}.

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}
