the answer in the procedure

step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

part a) find the distance between point r(3,7) and point s(−1,−4)

substitute the values

$d=\sqrt{(-4-7)^{2}+(-1-3)^{2}}$

$d=\sqrt{(-11)^{2}+(-4)^{2}}$

$d=\sqrt{121+16}$

$d=\sqrt{137}\ units$

part b) find the distance between point s(−1,−4) and point r(3,7)

substitute the values

$d=\sqrt{())^{2}+())^{2}}$

$d=\sqrt{(11)^{2}+(4)^{2}}$

$d=\sqrt{121+16}$

$d=\sqrt{137}\ units$
