## anonymous one year ago Find the slope of the line that contains the points named. J(1, -4), K(3, -1) 3/2 5/2 -3/2 The set of points P(0, 3), Q(2, 0), R(4, -3) are collinear. True False A triangle has vertices P(1, 3), Q(3, 5), and R(6, 2). The slope of the median to QR is 1/7 -1/2 1 The set of points W(4, 4), X(6, 2), Y(-8, 16) are collinear. True False The set of points R(-1, 1), S(2, 4), T(6, 8) are collinear. True False

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

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

Substitute the following to the formula. J(1, -4) x1 y1 K(3, -1) x2 y2
