Answer: It is a function

Step-by-step explanation: Every input has one output, so it’s a function. If this was asking whether the tables shows a linear relationship, the answer will be no, but this is asking whether it is a function.

What is the slope?

V125BC [204]

Answer:

$2$

Step-by-step explanation:

For this I would find two friendly points like (60,10) and (70,30). Now we will plug in for the slope-intercept formula $m=\frac{y_2-y_1}{x_2-x_1}$ .

So...

$y_2=30\\y_1=10\\x_2=70\\x_1=60$

Now we plug in and solve...

$m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{30-10}{70-60}\\m=\frac{20}{10}\\m=\frac{2}{1}=2$

So the slope will be 2.

Please help!

Ainat [17]

<span>(x – h)^2 + (y – k)^2 = r<span>^2

this equation is a derivative of the equation of a circle

x^2 + y^2 = r^2
This is from the origin. If we move the in x or y then the radius will change positions in x or y

with h = -3 and k = 1

we can plug in each set of numbers and solve.

we find Z to be on the circle edge!</span></span>
