Answer:
y=1/2x-2
Step-by-step explanation:
1. Find slop by subtracting y values over subtracting x values, which will get you the m value
-1+3 / 2+2 = 1/2
We use this formula to calculate the sum of all interior angles of a regular polygon; 180(n-2) , n= number of sides
so 180(5-2) = 540
each interior angle = 540 ÷ 5 = 108
