Question

These three points are collinear.

(3, 6), (-2, -9), (0, -4)

True
False

anonymous · Answer

Collinear points are points that lie on the same straight line. To see if these points lie on the same straight line, see if the slopes of any two points are equal. Use the formula to find the slope between two points, and see if all 3 points are collinear.

what do you mean?

amistre64 · Answer

the slope formula is:$$\frac{y_o-y_1}{x_o-x_1}$$

anonymous · Answer

the lines dont match so i guess its false?

amistre64 · Answer

if they dont match, its false

anonymous · Answer

ok thanks

amistre64 · Answer

my method would be to subtract one point from the other two, and compare

(3, 6), (-2, -9), (0, -4)
 0, 4     0 ,  4     0  ,4
--------------------
  3,10    -2,-5      0,0

10/3  not =  5/2
