Answer:
for the first one: y=1x and second one: y=-2
Answer: 5 8 7 9 5 6
Step-by-step explanation:
Because you go by which is closer to the denominator
Dependent variable is dependent on the independent variable
independent variable influences the dependentvariable
number of months influences the hcost
independent=number of months
dependent=cost
for the cost for 4 or 2 months, just start at months=2 or 4 and go up till you hit the line
equation=y=mx+b
m=slope
b=yintercept or starting point
solid line
initial fee=20
see attachment, black lines are what they are
2 months=$80
4months=140
rate is $30 per month
equation is c=30m+20
dashed line
intial fee=50
attachment, blue is dashed points
2months=$70
4months=$90
rate is $10 per month
equation is y=10x+50
Slopt in form ax+by=c is -a/b
-3/3=-1
slope is -1
intercept in form ax+by=c is c/b
63/3=9
slope is -1
intercept is at y=9
