b = 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Given

3x + y - 8 = 0 ( subtract 3x - 8 from both sides )

y = - 3x + 8 ← in slope- intercept form

with slope m = - 3

Given a line with slope m then the slope of a line perpendicular to it is

= - = - =

Consider the second line with equation

- 2x + by + 9 = 0 ← rearrange into slop- intercept form

by = 2x - 9 ( divide terms by b ( b ≠ 0 )

y = x - ← in slope- intercept form

with slope m =

Then

= ( cross- multiply )

b = 6
