Use the number line below, where RS = 9y + 2, ST = 2y + 3, and RT = 15y - 19. a. What is the value of y?
b. Find RS, ST, and RT.

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
