The slope-intercept form of the equation of a line that passes through point (–3, 8) is y = –2/3x + 6. What is the point-slope form of the equation for this line?

Respuesta :

To help you out, the equation for point slope form is y-y1 = m(x-x1)

You just plug the numbers in and solve. :)

y-8=-2/3(x+3)
y-8=-2/3x -2
y= -2/3x -2 -8
y=-2/3x - 10 is your answer.


Answer:

The point slope form of the line is [tex]y-8=-\frac{2}{3}(x+3)[/tex].

Step-by-step explanation:

The slope intercept form of a line is

[tex]y=mx+b[/tex]           .... (1)

where, m is slope and b is y-intercept.

The given equation is

[tex]y=-\frac{2}{3}x+6[/tex]          .... (2)

From (1) and (2) it is clear that

[tex]m=-\frac{2}{3},b=6[/tex]

The slope of the line is [tex]-\frac{2}{3}[/tex].

The point slope form of a line is

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

Where, m is slope.

The slope of the line is [tex]-\frac{2}{3}[/tex] and it passes through the point (-3,8).

[tex]y-8=-\frac{2}{3}(x-(-3))[/tex]

[tex]y-8=-\frac{2}{3}(x+3)[/tex]

Therefore the point slope form of the line is [tex]y-8=-\frac{2}{3}(x+3)[/tex].
