Answer:
yes to both
Step-by-step explanation:
For a relationship to be a function then each value of x must relate to exactly one unique value of y.
This is the case in this table as
2 → 76
4 → 152
6 → 228
All unique values thus a function
To determine if it is linear then the rate of change is constant for each set of ordered pairs. This is measured using the slope formula.
m =
with (x₁, y₁ ) = (2, 76) and (x₂, y₂ ) = (4, 152 ) ← ordered pair from table
m = = = 38
Repeat with (x₁, y₁ ) = (4, 152) and (x₂, y₂ ) = (6, 228)
m = = = 38
Since rate of change is constant then function is linear

Answer:
Step-by-step explanation:
First, the slope is determined by using the following expression:
The y-intercept is found by using the line equation, the slope and one point:
The equation of the line is:
sqrt (-1) = i the imaginary number
so the negative sqrt (-1) = -i
Yes they are because they contain the same slope
