Question

Find one possible missing coordinate so that the point becomes a solution to the given inequality. (x, 8) is a solution to 3x - 4 < y. X =

​

Answer 1

x = 0

Explanation:

Substituting the given "point" into the equation gives the possibilities for x.

Substitution

Using (x, y) = (x, 8), the inequality becomes ...

3x -4 < 8

Solving for x gives ...

3x < 12 . . . . . . . add 4

x < 4 . . . . . . . divide by 3

Any value of x less than 4 will make (x, 8) a solution to the inequality. For example, ...

x = 0 . . . . . . (0, 8) is a solution to the inequality
