Step-by-step explanation:
Given function is,
Where,
y = amount paid to the gym in dollars
x = number of months
So when x = 0, y =55(0)+80 = 80
i.e when number of months is 0, you have to pay a fee of $80.
This is the one time fee to open a membership.
After that for each month you have to pay $55 for each months.
So 55 is multiplied with x.
The Correct option is D). y=1x+1 And y=2x+2
Step-by-step explanation:
The equation of a line is given as y=mx+c.
where m=slope of line and c=y intercept
The slope of line is given as m=
Solving for Redline:
From the given graph, redline passes through (-1,0) and (0,1)
The slope of Redline is m=
The slope of Redline is m=
The slope of Redline is m=(1)
And Y-intercept is 1
The equation of a Redline is given as y=1x+1
Solving for Blue-line:
From the given graph, Blue-line passes through (-1,0) and (0,2)
The slope of Blue-line is m=
The slope of Blue-line is m=
The slope of Blue-line is m=(2)
And Y-intercept is 2
The equation of a Blue-line is given as y=2x+2
The Correct option is D). y=1x+1 And y=2x+2
