Suppose that f(x)=8x+1. Complete parts (a) through (f).
(a) What is the slope?
(b) What is the y-intercept?
(c) What is the zero of f?
(d) Solve f(x)=9. What point is on the graph of f? The solution to f(x)=9 is ____ (type an ordered pair)
The corresponding point on the graph is ____ (type an ordered pair)
(e) Solve f(x)≤-7. The solution is ____ (type your answer in interval notation)
(f) Graph f.
f(x) = 8x + 1 a) The slope is the number on the x which is 8 b) y-intercept is added (or subtracted) to the x which is 1 c) f(0) = 8(0) + 1 = 1 d) 9 = 8x + 1 8 = 8x x = 1 - solution (1, 9) - ordered pair e) -7 <= 8x + 1 -8 <= 8x -1 <= x {x | x => -1}
