The graph box linear function f passes through the point (1, -9) and has a slope of 3 what is the zero of f?

A) -2
B) 2
C) 4
D) -6

9514 1404 393

  C) 4

Step-by-step explanation:

The point-slope equation of the line is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y +9 = 3(x -1) . . . . . line with slope 3 through point (1, -9)

For y=0 (the 0 of the function), we have ...

  9 = 3(x -1)

  3 = x -1

  4 = x

The x-intercept is (4, 0).

answer: i think it is (1,-2)

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
