Question

4x + 20y = -180

Put the following equation of a line into slope intercept form, simplifying fractions

Answer 1

y = -
`(1)/(5)` x - 9

Explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

4x + 20y = - 180 ( subtract 4x from both sides )

20y = - 4x - 180 ( divide all terms by 20 )

y =
`(-4)/(20)` -
`(180)/(20)` , that is

y = -
`(1)/(5)` x - 9 ← in slope- intercept form
