Question

what does the notation r_y = 3x + 1(dab) mean? reflection rotation clockwise counter - clockwise around the origin to the axis over the x - axis over the y - axis over y = 3x + 1 180° 90° 270°

Explanation:

In transformation notation, R represents reflection. The sub - script indicates the line of reflection. So, $R_{y = 3x+1}$ means reflection over the line $y = 3x + 1$.

Answer:

Reflection over y=3x+1
