Question

18x+4y=122
Find the slope

Answer 1

slope = -
`(9)/(2)`

Explanation:

The equation of a line in slope- intercept form is

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

Rearrange 18x + 4y = 122 into this form

Subtract 18x from both sides

4y = - 18x + 122 ( divide all terms by 4 )

y = -
`(-18)/(4)` x +
`(122)/(4)` ← in slope- intercept form

with slope m = -
`(18)/(4)` = -
`(9)/(2)`
