7. Which set of points could represent a linear function?
A {(2, 1), (5,3), (6, 7), (7, 11)}
B ((2.-1), (5,3), (8, 7). (11.11 )}
C {(2, -1), (5,5), (8,7), (11, 11 )}
D (5.-1), (5,5), (8,7), (11, 11)}

B ((2.-1), (5,3), (8, 7). (11.11 )}

Step-by-step explanation:

Linear function:

The rate of change is always the same.

Item a:

x = 2 to x = 5 -> y = 1 to y = 3. Rate of change of 2/3.

x = 5 to x = 6 -> y = 3 to y = 7. Rate of change of 4.

Different rates of change, so not linear.

Item b:

We can look that for each point, when x changes by 3, y changes by 4, so the rate of change is the same and this set of points represents a linear function, and the answer is option b.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
