Write an equation for the line that passes through (-8.5, 11) and (5, -2.5).

9514 1404 393

  y = -x + 5/2

Step-by-step explanation:

The 2-point form of the equation of a line can be useful.

  y = (y2 -y1)/(x2 -x1)/(x -x1) +y1

  y = (-2.5 -11)/(5 -(-8.5))/(x -(-8.5)) + 11

  y = -13.5/13.5(x +8.5) +11 . . . . . . simplify a bit

  y = -x +2.5 . . . . . write in slope-intercept form

i think the correct option is the second option.

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
