10 points for the first write answer i need what is the slope of the line? enter your answer, in simplest form.

Using the two points given on the graph, the slope is the change in y over the change in x.

Change in Y: 8-5 = 3

Change in X: 2-1 =1

Slope = 3/1

In simplest form, the slope = 3.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

i believe the answer is the polygon, heptagon.
