Answer:
A. $100
Step-by-step explanation:
y = 0.2x +300
0.2(500) + 300 = 400
0.2(1000) + 300 = 500
9x +5y= -45
put in standard form
y= mx+b
coefficient of x is the slope, b is the y intercpept
5y= -9x -45
y= -9/5 x -45
graphing will start at -45 on the y axis
from that point go down 9 to the right 5 for the slope continue and graph minimum
2 points to draw the line
hope this helps
