IR, US, and OB are all medians of A BRS, and T is the centroid. IR = 10.8', BT = 4.5', UT = 3.15'. Find RT, TI, OB, and US.

4. (10.03 mc) the equation of line cd is y = −2x − 2. write an equation of a line parallel to line cd in slope-intercept form that contains point (4, 5). (4 points) y = −2x + 13 y = negative 1 over 2 x + 7 y = negative 1 over 2 x + 3 − 2x − 3
