3y-12x=24 and goes through point (2,-6) . write your answer in y=mx+b
Masteriza [31]

Answer:

y= 4x+8

Step-by-step explanation:

Add 12x to both sides.

3y=24+12x

The equation is in standard form.

3y=12x+24

Divide both sides by 3.

3

3y

​

=

3

12x+24

​

Dividing by 3 undoes the multiplication by 3.

y=

3

12x+24

​

Divide 24+12x by 3.

y=4x+8

Write an equation With the slope equal to -4/5 and (0,8)
Murljashka [212]

Answer: y = (-4/5)x + 8

Solution

The equation of line is

y = mx + b

Where

y = y coordinate

m = slope

x = x coordinate

b = y intercept

In order to write the equation of line we need to find the y-intercept (b)

substitute the slope (-4/5)  and coordinates given (0,8) ,

y = mx + b

8 = -4/5 (0) + b

8 = b

So,

y = (-4/5)x + 8
