True
False

The set of points R(-1, 1), S(2, 4), T(6, 8) are collinear.

True
False

Answer 1

Use the slope formula for the first question.
\[\large m=\frac{ y _{2}-y_{1} }{ x_{2}-x_{1} }\]

Answer 2

this looks really familiar... im not good at this soo

Answer 3

Substitute the following to the formula.

J(1, -4)
x1 y1

K(3, -1)
x2 y2
