Answer:The solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality.
Example
Is (1, 2) a solution to the inequality
2x+3y>1
2⋅1+3⋅2>?1
2+5>?1
7>1
The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.

Answer:
2 * -4 = -8
Step-by-step explanation:
2 * -4 = -8
It is just like multiplying two numbers like... 2 * 4 = 8
You must need to know that:
+a * -b = -c
-a * -b = +c
+a * +b = +c
In your question;
+a * -b = -c
a = 2
b = -4
c = -8
therefore:
2 * -4 = -8
