Can someone please help me with math

3. B

4. D

Step-by-step explanation:

3. The y-intercept is -4 and the slope is positive 2.

4.Substitute the values and check

Answer and Step-by-step explanation:

3.

Before we look at the answer choices, lets analyze the graph.

We see that as the graph goes right, the y values are positive, and that as the graph goes left, the y values become negative/decrease. (Graph, as in the line on the graph).

That means the graph has a positive slope. So we can get rid of any negative slopes (answer choices A and C).

Now, we look to see the rate of change of the graph. How many units does the graph go up and right right?

We see that the graph has a rate of change of 2, so that is the slope.

This means that answer choice B is the answer. The equation shows that it goes down 4 units as well, which is what the graph shows as well.

4.

For this one, we need to see the pattern in the table.

When we put 2 in for n, we get 6. When we put 3 in for n, we get 8. And when we put 4 in for n, we get 10.

Answer choice D works for this. If we plug 2, 3, and 4 in for this expression, we get:

2(2) + 2 = 4 + 2 = 6

2(3) + 2 = 6 + 2 = 8

2(4) + 2 = 8 + 2 = 10

So answer choice D is the answer.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
