Question

. The points given in the table lie on a line. Find the slope of the line.

Answer 1

Answer:

-12 / 17

Step-by-step explanation:

x | -1 | 2 | 5 | 8 |

-----------------------

y | 3 | -1 | -5 | -9 |

Piking the poits at the extreme:

x1 = - 1 ; y1 = 3

x2 = 8 ; y2 = - 9

Slope = Rise / Run

Rise = y2 - y1 = - 9 - 3 = - 12

Run = x2 - x1 = 8 - (-9) = 8 + 9 = 17

Hence,

Slope = - 12 / 17
