I believe it's not a function because the input (x) 4 has two outputs(y), 2 and 8.
Answer:
-8x + 5y + 4
Step-by-step explanation:
- 6x + 5y - 2x + 4 Group like terms
-6x - 2x + 5y + 4
= - 8x + 5y + 4
Answer:
-4 < n ≤ 5
Step-by-step explanation:

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
