Question

- Rewrite - 7x +9y = 18 in slope-intercept form. Identify the slope and y-intercept

of the line.

Answer 1

see explanation

Explanation:

The equation of a line in slope- intercept form is

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

Rearrange - 7x + 9y = 18 into this form

Add 7x to both sides

9y = 7x + 18 ( divide all terms by 9 )

y =
`(7)/(9)` x + 2 ← in slope- intercept form

with slope m =
`(7)/(9)` and y- intercept c = 2
