Can someone please help me ASAP? What are the points? Point: (_, _)

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form. −three fourthsx + y = 10 3x − 4y = −40 y = three fourthsx + 12 y = three fourthsx + 10
