Consider the equation 12x - 5y = 15
a. write the equation in slope intercept form
b. what is the slope?
c. what is the y-intercept​

Respuesta :

Answer:

Slope-Intercept Form - y = 12/5x-3

Slope - M = 12/5

The Y-Intercept - B = -3

For finding slope use formula and y-intercept use y=mx+b

m=Slope

b=y-intercept

Answer:

(a) Slope intercept form : [tex]y=\dfrac{12}{5}x-3[/tex]

(b) Slope = 12/5

(c) y-intercept: -3

Step-by-step explanation:

(a)

Slope intercept from of a line is

[tex]y=mx+b[/tex]         ..... (1)

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

The given equation is

[tex]12x-5y=15[/tex]

Subtract 12x from both sides.

[tex]-5y=-12x+15[/tex]

Divide both sides by -5.

[tex]y=\dfrac{-12x+15}{-5}[/tex]

[tex]y=\dfrac{12}{5}x-3[/tex]       .... (2)

Therefore, the slope intercept form is [tex]y=\dfrac{12}{5}x-3[/tex].

(b)

On comparing (1) and (2) we get

[tex]m=\dfrac{12}{5}[/tex]

The slope of the equation is 12/5.

(c)

On comparing (1) and (2) we get

[tex]b=-3[/tex]

The y-intercept of the equation is -3.
