Step-by-step explanation:
× Jorge should graph in the vertical line with values of –4 for the line of reflection. (The line of reflection is horizontal.)
→ Jorge could count how far each pre-image point is from the line of reflection along the perpendicular from the point to the line of reflection.
× Jorge could count how far each vertex of the figure is from the y-axis and count the same distance on the other side. (He could do this pointless exercise, but it has no relation to the problem. The y-axis (x=0) is not the line of reflection.)
→ Jorge will not move any point that lies on the line of reflection. (All points on the line of reflection are reflected to themselves.)
→ Jorge could check his work by seeing if each segment joining a pre-image point with its image has the midpoint on the line of reflection. (This is what is meant by "line of reflection.")
× Jorge could check his work by making sure that the image has the same orientation as the original. (A reflected image as an orientation opposite that of the original, a fact you see every time you look in a mirror.)

Answer:
The rate is
degree per hour.
Step-by-step explanation:
Given : A scientist conducted an experiment. Due to chemical reaction, the temperature of a compound rose
degree every
hour for a limited time.
To find : What was the rate, in degrees per hour that the temperature of the compound rose ?
Solution :
In every
hour the temperature of a compound rose
degree
To get the rate, in degrees per hour,
In every 1 hour the temperature of a compound rose is
degree
degree/hr
degree/hr
Therefore, the rate is
degree per hour.
