The set of points r(-1, 1), s(2, 4), t(6, 8) are collinear and the line has a slope of

a.-1
b.1/2
c.1
d.-1/2

OptionC

Step-by-step explanation:

Let the point R and S form a line.

The slope of line RS would be

Change in y coordinate/change in x coordinate

=

Now let us consider the line joining S and T

slope of line ST would be

=Change in y coordinate/change in x coordinate

=

Thus we find the slopes of RS and ST are equal

Since parallel lines will have equal slopes, here S is the common point

So RS and ST have to be the same line.

Or the three points are collinear with slope = 1

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.
