Answer:
75%
Step-by-step explanation:
Percent yield = experimental yield / theoretical yield * 100
= 900 / 1200 * 100 (remember that 1,000 g = 1 kg)
= 75
Given equation is 
If we substitute x = 0, then, y = - 4.
So, (0, -4) is a point on the line.
If we substitute x = - 6, then y = 5 - 4 = 1.
So, (-6, 1) is another point on the line.
Joining (0, -4) and (-6, 1), we get the graph of the line.
