Answer:

Step-by-step explanation:

11 is angle somethingSQ is equal to angle QSR. 12 is something about the division property of equality
The general equation of a line is y = mx+b. The line is horizontal and the slope (m) of a horizontal line is 0. So y = 0x + b = b. Since the y intercept (where it crosses the y axis) is -1 (or b = -1) then you have the equation y = -1.
Answer: y = -1.
