Answer:
f(x) = -5x - 1.
Step-by-step explanation:
The y values are decreasing by 5 as the x values increase by 1, so it looks like a linear function.
The slope = (4-9) / (-1 - (-2)) = -5 so we write:
y = -5x + c where c is the y-intercept.
When x = 0, c = -1 so the function is
f(x) = -5x - 1.
Answer:
(30,0)
Step-by-step explanation:
y=0
-2/5 *x +12=0
2x/5=12
2x=12*5
2x=60
x=60/2
x=30
which is true so you're right
