See the solution process below:

To find three solutions to this equation, substitute three different numbers and calculate the result for #y#:

1) Set #x = 0#

#y = 9x - 4# becomes:

#y = (9 * 0) - 4#

#y = 9 - 4#

#y = 5#

The first solution is: #(0, 5)#

2) Set #x = 10#

#y = 9x - 4# becomes:

#y = (9 * 10) - 4#

#y = 90 - 4#

#y = 86#

The second solution is: #(10, 86)#

3) Set #x = -10#

#y = 9x - 4# becomes:

#y = (9 * -10) - 4#

#y = -90 - 4#

#y = -94#

The third solution is: #(-10, -94)#
