What are the coordinate points of E′ if E(−9, 8) is translated left 13 units, then up 21 units?
To find the coordinate points of E′, we first translate E(-9, 8) left 13 units. This means we subtract 13 from the x-coordinate of E to get the new x-coordinate for E′:
New x-coordinate = -9 - 13 = -22
Next, we translate E′ up 21 units. This means we add 21 to the y-coordinate of E′ to get the final coordinate points for E′:
New y-coordinate = 8 + 21 = 29
Therefore, the coordinate points of E′ are (-22, 29).
