Dovator [93]

Answer:

C

Step-by-step explanation:

The equation of a line is given by y-y_1=m(x-x_1)

and

slope (m) is given by:

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

Where (x_1,y_1) are the first set of point in the line and (x_2,y_2) is the second set of point

<em>Let's take 2 points arbitrarily. (0,0) & (25,20)</em>

<em />

<em>Let's plug it and find the equation:</em>

<em>m=\frac{20-0}{25-0}=0.8</em>

<em>Now</em>

<em>y-y_1=m(x-x_1)\\y-0=0.8(x-0)\\y=0.8x</em>

<em />

<em>C is the correct answer.</em>

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).
Gwar [14]

Answer:

The answer to your question is slope = 0; y = -2

Step-by-step explanation:

Data

A (-2, -2)

B (2, -2)

Process

1.- Calculate the slope

    m = (-2 - (-2)) / (2 - (-2))

    m = ( -2 + 2) / (2 + 2)

    m = 0/4

    m = 0

2.- The equation of the line is

    y - y1 = m(x- x1)

     y - (-2) = 0(x - (-2))

     y + 2 = 0

     y = -2
