What is the slope intercept equation of this line? (0,6) (4,-2)

A. Y= -1/2 x + 6
B. Y= -2x + 6
C. Y= 6x - 2
D. Y= 2x + 6

Respuesta :

Answer:

B. Y= -2x + 6

Step-by-step explanation:

(0,6) (4,-2)

Slope = (6 + 2)/(0 - 4)

=8/ -4

=  -2

y intercept = 6

Equation:

y = -2x + 6

Answer

 B. Y= -2x + 6

Answer:

B. Y= -2x + 6

Step-by-step explanation:

The given line passes through; (0,6) and (4,-2).

The slope-intercept equation of this line is given by;

[tex]y=mx+c[/tex]

Where m is the slope and c is the y-intercept.

The slope is calculated using the formula;

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

Let [tex](0,6)=(x_1,y_1)[/tex] and [tex](4,-2)=(x_2,y_2)[/tex].

Then;

[tex]m=\frac{-2-6}{4-0} =\frac{-8}{4}=-2[/tex]

The point (0,6) is the y-intercept because the x-coordinate is 0, hence c=6.

The equation is ;

[tex]y=-2x+6[/tex]

The correct choice is B.
