No, because it has a constant rate of change
By looking at this table
The y value changes at a constant multiple of 2
6 4
7 2 (4-2 is a difference of 2)
8 0 (2-0 is a difference of 2)
9 -2 (0-2 is a difference of 2)
This means it is Linear
False, they have a different slope and y intercept
If the question is y = blank(x) + blank (I can’t see the left of the equation
Then the answer is y = 2x + -4
No,
although all the sides are the same length on an equilateral triangle the height is calculated by a straight perpendicular line at the mid point of the base.
The sides are not perpendicular with the base and are angled outwards
