Equation of the line is ---> y = -4x + 4
-4 = slope (For every increase in x, y decreases by 4)
+4 is the y-intercept (When x = 0, y = 4)
If you want the equation for each individual x or y coordinate, look below.
(0,4) (1,0) (2,-4) (3,-8)
X values in order: 0, 1, 2, 3
Y values in order: 4, 0, -4, -8
The X-values start at 0, and increase by 1 every time.
The Y-values start at 4, and decrease by 4 every time.
Equation:
(0+n, 4 - 4n)
Where n is the numbered term, EX: n = 1 is (0,4), n = 2 is (1,0), n = 3 is (2, -4), n + 4 is (3, -8), ...
