Topic 7 of "DSAT Math: The Essential Concepts." Learn how translations slide a graph left, right, up, and down, and how reflections flip it across the x-axis or y-axis, so you can write the new equation or find a new intercept on the Digital SAT. Then watch two SAT-style questions solved step by step.

0:00 Two big ideas
0:15 Translations: sliding a graph
1:30 Reflections: flipping a graph
2:26 Recap
2:37 Your turn: try Examples 1 & 2
3:21 Example 1: shift a line 2 units down, find the x-intercept
5:30 Example 2: shift 9x + 15y = 90 left 3 units, find the y-intercept
✏️ Practice problems in this video
Example 1: A table gives three points on line p. Line q is line p translated 2 units down. What is the x-intercept of line q?
Example 2: The graph of 9x + 15y = 90 is translated 3 units to the left. What is the y-coordinate of the new y-intercept?
