The graph of a line passes through the points (0, -2) and (6.0). What is
the equation of the line?

Respuesta :

Answer:

[tex]y=\frac{1}{3}x-2[/tex]

Step-by-step explanation:

The equation of a line is given in the form  [tex]y=mx+b[/tex]

Where

m is the slope with formula  [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

and

b is the y-intercept [y axis cutting point of line]

Given the two points (0, -2) and (6,0),

x_1 = 0

y_1 = -2

x_2 = 6

y_2 = 0

Now, we find m using formula:

[tex]m=\frac{0+2}{6-0}=\frac{1}{3}[/tex]

Now we have

[tex]y=\frac{1}{3}x+b[/tex]

Finding b, we plug in any (x,y) point. Lets put (6,0) and find b:

[tex]y=\frac{1}{3}x+b\\0=\frac{1}{3}(6)+b\\0=2+b\\b=-2[/tex]

Thus,

equation of line = [tex]y=\frac{1}{3}x-2[/tex]
