1. Determine whether the points (-5,8) and (-5,-4) lie on the same horizontal or vertical line. Explain how you know. Then, find the length of the line segment that connects them. 2. Skye’s city is on a grid like the coordinate plane. He unicycles from point (11,15) to point (11, -12). How many units does he travel? Explain how you found your answer using absolute value.

the answer is 37

step-by-step explanation:

you answer is a

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
