Which equation is a point slope form equation for line AB y12x6 y22x5 y62x1 y52x2 class=

Respuesta :

Answer:

Option 2: y+2=−2(x−5) is the correct answer.

Step-by-step explanation:

We can see two points on the line A and B.

Their coordinates are:

A = (x1,y1) = (1,6)

B = (x2,y2) = (5,-2)

The point slope form is given as:

[tex]y-y_1 = m(x-x_1)[/tex]

Here m is the slope which is found using the formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Putting the values

[tex]m = \frac{-2-6}{5-1}\\m=\frac{-8}{4}\\m = -2[/tex]

Putting the value of slope

[tex]y-y1 = -2(x-x_1)[/tex]

Putting both points to get two forms of point slope form of equation

Putting (1,6):

[tex]y-6 = -2(x-1)[/tex]

Putting (5,-2):

[tex]y+2 = -2(x-5)[/tex]

Looking at the equations and options it can be concluded that

Option 2: y+2=−2(x−5) is the correct answer
