Answer:
x ≤ -5
Step-by-step explanation:
Inequalities' line graphs commonly show the range of values of a singular variable rather than a linear function like 3x + 80 so, rearranging the given inequality for x is best to be able to graph it with ease.
3x + 80 ≤ 65
3x ≤ -15 (Subtract 80 both sides)
x ≤ -5 (divide both sides by 3).
Since the inequality symbol is a less than or equal to sign that means that the range of x values that satisfy this expression includes -5 thus, the line graph will have a closed hole. All the other values in x's range are "more negative" than -5 like -7, -10, -20, -∞ so, the line will point to the left of -5.
