Answer:

(2,-6)

Step-by-step explanation:

The solution set is any point to the left of the line. To find the solution set, test a point like (0,0).

$3(0) + 4(0) \leq -1\\0\leq -1\\False$

This means (0,0) is not in the solution set. The solution set is the region to the left of the line. Any point in this area will be a solution.
