The solution to the inequality 149.76 > -19.2x is dashed line at x = -7.8 which includes all region greater than x = -7.8.
How to plot inequality graph
Given
149.76 > -19.2x
find x
Isolate the variable:
-19.2x < 149.76
Divide by the coefficient (-19.2), remembering to reverse the inequality sign when dividing by a negative number
x > 149.76/-19.2
Calculate the result
x > -7.8
Since x is greater than -7.8, we will mark all values greater than -7.8, and use an dashed line to indicate that -7.8 itself is not included:
The solution to the inequality 149.76 > -19.2x is dashed line at x = -7.8 which includes all region greater than x = -7.8.
