Question

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

2x+2y=18

Answer 1

y = - x + 9

Explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given the line with equation

2x + 2y = 18 ( subtract 2x from both sides )

2y = - 2x + 18 ( divide through by 2 )

`(2)/(2)` y =
`(-2)/(2)` x +
`(18)/(2)` , that is

y = - x + 9 ← in slope- intercept form
