Answer:

-2

Step-by-step explanation:

slope =

(y2-y1)÷(x2-x1)=

(3-1)÷(0-1) <em><u>or</u></em> (1-3)÷(1-0) = -2

State the equation of the line described.
Stells [14]

Answer:

y = mx + b

Since it is perpendicular to the given line, its slope is the negative reciprocal of the slope of the given line.

Slope of given line:

m0 = -a/b = -(-3) / (1) = 3

Slope of perpendicular line:

m = -1/3

y = (-1/3)x + b

Use the given point to find b.

2 = (-1/3)(3) + b

2 = -1 + b

b = 3

y = (-1/3)x + 3

A line passes through (2, 8) and (4, 12). Which equation best represents the line? y = 1 over 2 x 6 y = 2x 7 y = 2x 4 y = 1 over
nalin [4]

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

Given information-

The point through which the line passes are (2, 8) and (4, 12).

To find the equation of the line, the standard form of the equation of the line must be obtained.

<h3>Equation of the line</h3>

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

The standard form of the equation of the line can be given as,

(y-y_1)=\dfrac{y_2-y_1}{x_2-x_1} (x-x_1)

Where (x_1,y_1) and (x_2,y_2) are the points through which the line passes.

Thus the equation of the line which passes through the points (2, 8) and (4, 12) can be given as,

(y-8) &=\dfrac{12-8}{4-2} (x-2)\\(y-8) &=\dfrac{4}{2} (x-2)\\2y-16 &=4x-8\\2y &=4x-8+16\\

Divide by 2 both the side,

y=2x-4

Thus the equation of the line which passes through the points (2, 8) and (4, 12) is,

y=2x-4

Hence the option 3 is the correct option.
