When graphing a linear inequality, how do you know if the line should be dotted or solid?

i hope this helps  :)

Step-by-step explanation:

if you are going to graph an inequality, then treat the  ≤, <, >, or ≥ sign as an = sign, and then graph the equation. If the equation says the inequality is < or >, then graph the equation as a dotted line. If the equation says the inequality is ≤ or ≥, then you are going to graph the equation as a solid line.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
