A data set contains an independent and a dependent variable. Which must be true of the data set if a linear function can be used

ycow [4]

The set must have a constant additive rate of change.

Answer: Option A.

Explanation:

A function has an additive rate of change if there is a consistent distinction between any two successive information and yield esteems. From the primary table we can watch a consistent distinction of - 6 among the y-values and a steady contrast of 2 among the x-values.

A linear function has a consistent additive rate of change, while a nonlinear capacity doesn't. For a table of qualities to be direct, the needy variable must have a steady pace of progress as the autonomous variable increments by 1.

Which two lines are parallel? Which two lines are perpendicular?

lana66690 [7]

Answer:

see explanation

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

All the equations given are in slope- intercept form

y = 2x + 1 → with m = 2

y = $\frac{1}{2}$ x - 4 → with m = $\frac{1}{2}$

y = x + 1 → with m = 1

y = - $\frac{1}{x}$ x - 3 → with m = - $\frac{1}{2}$

y = 10 + x → y = x + 10 → with m = 1

Thus

y = x + 1 and y = 10 + x are Parallel since both have m = 1

y = 2x + 1 and y = - $\frac{1}{2}$ x - 3 are Perpendicular since 2 × - $\frac{1}{2}$ = - 1
