Answer:
x y
0 9
1 12
Step-by-step explanation:
Use the slope-intercept form to find the slope and y-intercept.
Slope:
3
y-intercept:
9
Any line can be graphed using two points. Select two
x
values, and plug them into the equation to find the corresponding
y
values.
Choose
0
to substitute in for
x
to find the ordered pair.
y
=
9
Choose
1
to substitute in for
x
to find the ordered pair.
y
=
12
Create a table of the
x
and
y
values.
x

Perimeter is 40 and area is 60 something. Sorry if I’m wrong I tried to help you tho. But If I am wrong look at other people’s answers
Answer:
See below
Step-by-step explanation:
1. 12
2. 15 [3*12-21 = 15]
3. 24 [3*15-21 = 24]
4. 51 [3*24 - 21 = 51]
(5,22.45),(7,25.45)
slope = (25.45 - 22.45) / (7 - 5) = 3/2 or 1.5
y = mx + b
slope(m) = 1.5
use either of ur points...(5,22.45)...x = 5 and y = 22.45
now sub and find b
22.45 = 1.5(5) + b
22.45 = 7.5 + b
22.45 - 7.5 = b
14.95 = b
so ur equation is : y = 1.5x + 14.95.......this means that each quart of oil costs $ 1.50 and the labor fee costs $ 14.95
