In Exercises 1 to 4, use division to write an equation of the form A x + B y = C that is equivalent to the one provided. Then write the given equation in the form y = m x + b . - 6 x + 18 y = - 240

To determine

Express the equation -6x+18y=-240 in the form y=mx+b.

Explanation

The given equation is expressed in the standard form as given below.

Add 6x to each side of the equation -6x+18y=-240

-6x+18y+6x=-240 6x

6x and -6x on left hand side get cancelled.

Then,

18y=-240 6x

Rewrite the equation 18y=-240 6x as

18y= 6x-240

Now, divide 18y= 6x-240 by 18

So,

18y18=6x18-24018

Here,

18y18=y

6x18=13
