Identify the pair of lines as parallel or perpendicular.
1. f(x) = 2x + 3
g(x) = -1/2x + 3

2. f(x) = 1/3x + 4
g(x) = 1/3x + 5

1.  Perpendicular

2.  Parallel

Step-by-step explanation:

A line is parallel to another if it has the same slope

A line is perpendicular to another if it has the opposite reciprocal of the other slope.

1.  f(x) = 2x + 3

   f(xx) = -1/2 + 3

Perpendicular

2.  f(x) = 1/3x + 4

    g(x) = 1/3x + 5

Parallel

Step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
