The point-slope form equation for this line is y₁ - 9 = 4 (x₁ - 1), or D.

Since these are all in point-slope form, all we need to do is find the slope and then input one value of (x, y) into the points. We start with the slope.

m = \frac{y₁ - y}{x₁ - x}

m = \frac{3 - 9}{-2 -1}

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

m = 2

Now we need to input the values of one of the points and slope into the point slope equation: y₁ - y = m(x₁ - x). 

Inputting (1, 9), we get

y₁ - 9 = 4 (x₁ - 1)

The equation that fits it is D., so that means that the only answer to this question is D.

Solve the system of equation by the addition method x-2y=11 and -x+6y =-31
Sonbull [250]

Answer: x = 1, y = - 5

Step-by-step explanation:

The given system of linear equations is expressed as

x - 2y = 11- - - - - - - - - - - - -1

- x + 6y = - 31- - - - - - - - - - - -2

We would eliminate x by adding equation 1 to equation 2. It becomes

- 2y + 6y = 11 - 31

4y = - 20

Dividing the the left hand side and the right hand side of the equation by 4, it becomes

4y/4 = - 20/4

y = - 5

Substituting y = - 5 into equation 1, it becomes

x - 2 × - 5 = 11

x + 10 = 11

Subtracting 10 from the left hand side and the right hand side of the equation, it becomes

x + 10 - 10 = 11 - 10

x = 1

"Linear function" means the highest degree of any term is 1.

Equation 1: degree is 2
Equation 2: degree is 2
Equation 3: degree is 1 . . . . this is your linear function
Equation 4: degree is 4
