Question

Solve -3x + 1 > 4 and describe the graph of the solution.

Answer 1

x < -1

Question: are we graphing on a number line or in 2-space with x-y plane?

Answer 2

-3x + 1 > 4
-3x + 1 - 1 > 4 - 1
-3x > 3
x < -1

Note that when dividing an inequality by a negative number, the order of the inequality is reversed.

Answer 3

x y plane

Answer 4

Okay

Answer 5

The line x = -1 is dashed to indicate that it is not included in the solution set.
