Two points on L₁ and two points on L₂ are given. Determine if lines L₁ and L₂ are parallel, perpendicular, or neither.

L_1: (-7, 3) and (1, 8)

L_2: (2, 9) and (-6, 4)

Write the lines in slope-intercept form and state whether they are parallel, perpendicular, or neither.

5y - 2x = -3

2y + 5x = 9

Determine whether the relation represents a function or a nonfunction. If the relation is a nonfunction, pls explain how the definition of a function is violated.

{(-8, -9), (-11, -8), (-6, -11), (-9, -6), (-11, -10), (-4, -12)}

function

or

Not a function; -11 is paired with -8 and -10.
