M must equal 20 to make the function to be linear

Answer:

The correct option is 4.

Step-by-step explanation:

If a line passing through two point, then the slope of the line is

slope=\frac{y_2-y_1}{x_2-x_1}

From the given table it is clear that the line passing through the points (4,26), (5,23) and (6,m).

Line passing through (4,26) and (5,23). So, the slope of the line is

slope=\frac{23-26}{5-4}=-3

The slope of line is -3.

Line passing through (4,26) and (6,m), and the slope of the line is -3.

slope=\frac{m-26}{6-4}

-3=\frac{m-26}{2}

Multiply both sides by 2.

-6=m-26

Add 26 on both the sides.

-6+26=m

20=m

The value of m is 20 and because the rate of change is –3.

Therefore the correct option is 4.

Find the midpoint of the line segment joining the points R(-5,5) and S(4.6).
tigry1 [53]

Hey there! I'm happy to help!

To find the x value of the midpoint, you add the x values and divide by 2.

-5+4=-1

-1/2=-1/2

For the y value, you add the y values and divide by 2.

5+6=11

11/2=5 1/2

So, the midpoint is (-1/2, 5 1/2).

Have a wonderful day! :D
