Answer

(-1, 2) Explanation 1. Calculate the vector from R to S The vector \overrightarrow{RS} is calculated as (2 - (-7), 4 - (-2)) = (9, 6). 2. Scale the vector by \frac{2}{3} Multiply the vector (9, 6) by \frac{2}{3} to get \left(\frac{18}{3}, \frac{12}{3}\right) = (6, 4). 3. Find point Q Add the scaled vector (6, 4) to point R(-7, -2) to find Q: (-7 + 6, -2 + 4) = (-1, 2).

Explanation

1. Calculate the vector from R to S<br /> The vector $\overrightarrow{RS}$ is calculated as $(2 - (-7), 4 - (-2)) = (9, 6)$.<br />2. Scale the vector by $\frac{2}{3}$<br /> Multiply the vector $(9, 6)$ by $\frac{2}{3}$ to get $\left(\frac{18}{3}, \frac{12}{3}\right) = (6, 4)$.<br />3. Find point Q<br /> Add the scaled vector $(6, 4)$ to point $R(-7, -2)$ to find $Q$: $(-7 + 6, -2 + 4) = (-1, 2)$.
