Answer:

neither a or b

Step-by-step explanation:

a function has to have each X have a Y

a domain is paired with exactly one range value.

it has to pass the vertical line test

independent variable is X

dependant variable is Y

student name = x

colors/teachers is Y

so since there is the chance the students can have the same teacher and/or favorite color. then it is not a function

Find the equation of the line that passes through (3,1) and is parallel to y=2x+1.

creativ13 [48]

9514 1404 393

Answer:

y = 2x -5

Step-by-step explanation:

The parallel line will differ only in the value of c. That can be found using the given point.

y = mx +c

c = y -mx . . . . . . subtract mx to solve for c

c = 1 -2·3 = -5 . . . . . . the value of m is 2 in the given equation (x, y) = (3, 1)

The equation of the parallel line is ...

y = 2x -5
