Answer:

The y-intercept is 17.

Explanation:

We can find the y-intercept by solving for #y# and putting this equation into the slope-intercept form.

The slope-intercept form of a linear equation is:

#y = color(red)(m)x + color(blue)(b)#

Where #color(red)(m)# is the slope and #color(blue)(b# is the y-intercept value.

#y - 9x + color(red)(9x) = color(red)(9x) + 17#

#y - 0 = 9x + 17#

#y = 9x + 17#

This is now in the slope-intercept form:

#y = color(red)(9)x + color(blue)(17)#

Where #color(red)(9)# is the slope and #color(blue)(17)# is the y-intercept value.
