Answer:
y = -3x + 5
Step-by-step explanation:
A parallel line has the same slope. y=mx+b where m is the slope. The reference line is y=-3x-5, sio the slope is -3 and any parallel line must have the same slope. The eliminates the second answer (slope is 3, not -3). The equation must "satisfy" the requirement that point (1,2) is on the line (i.e., it is a solution. We know the line must have the form y= -3x+b, so we need b. Find the value of b by entering (1,2) and solving for b:
y= -3x+b
2 = -3*1 + b
b = 5
The equation is y = -3x + 5
