Question

Attached. What is special about these points?

Answer 1

P=(1,3)
Q= (5,6)
R=(11.4, 10.8)

Answer 2

You could find the slope of the line between P and Q
Then find the slope of the line between Q and R
If both slopes are the same then you know that P, Q and R are collinear (i.e. they lie on a straight line)

Answer 3

Ratios are 4:3 for successive points so linear.

Answer 4

They're collinear, I think. Their slopes all equal 3/4.

Answer 5

If slope are the same, then yes, they must be collinear.

Answer 6

So how do I find the line they are on?

Answer 7

You know the slope, and you know at least one point that the line passes through

Answer 8

oh yeah!

Answer 9

Make use of the general equation of a line given as:\[y=mx+c\]where m is the slope of the line.

Answer 10

:)

Answer 11

y=3/4x + 2.25

YAYYYY thanks

Answer 12
