Answer:

Third option

m = 2.25

Step-by-step explanation:

The slope of the function is equal to its rate of change between two points.

For example, for a couple of points $(x_1, y_1),\ (x_2, y_2)$

The slope is:

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

In this problem we have the following points

1.(2, 8.50) , 2. (5, 15.25), 3. (8, 22.00) , 4. (12, 31.00)

We calculate the slope between the first two points

$m =\frac{15.25-8.50}{5-2}=2.25$

We calculate the slope between the points 3 and 4

$m =\frac{31-22}{8-4}=2.25$

We calculate the slope between the points 2 and 3

$m =\frac{22-15.25}{8-5}=2.25$

The slope is always the same. Therefore m is constant and the fution is a line of slope m = 2.25

Solve the system of equations algebraically.<br> 4x - 3y = 6<br> 6x - 5y = 6

Answer: x=6 y=6

Step-by-step explanation:

$\displaystyle\\\left \{ {{4x-3y=6} \atop {6x-5y=6}} \right.\\$

Since the right parts of the equation are equal, therefore the left parts of the equation are also equal:

$4x-3y=6x-5y\\4x-3y+5y=6x-5y+5y\\4x+2y=6x\\4x+2y-4x=6x-4x\\2y=2x\\$

Divide both parts of the equation by 2:

$y=x\\Hence,\\4x-3x=6\\x=6\\Thus,\\x=y=6$

Question 4 of 10

soldi70 [24.7K]

Answer:

d. y=5x-3

Slope-intercept form is y=mx+b.

m= slope

b= y intercept

so, m=5 and b= -3

Substitute with those values and then you have the equation.
