Four times a number, minus six, is eight. 4(z - 6) = 8
4z - 6 = 8
6 - 4z = 8
4(6 - z) = 8

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
