Answer:
$42.26
Tom spent more on tax ($1.54 vs his cousin's $0.72)
Step-by-step explanation:
Tom: $22 x 1.07 = $23.54
tax spent = 22 x 0.07 = $1.54
Cousin: $18 x 1.04 = $18.72
tax spent = 18 x 0.04 = $0.72
Total= $23.54 + $18.72 = $42.26
C. 1/5,2/5,3/5,4/5 and 1 since all will be on the same mark as 2/10,4/10,6/10,8/10 and 10/10.
d. there would be 10/10 for every 0 to 2.
25 divided by 60 would be .416 repeating, rounded to .417
60 divided by 25 would be 2.4
Add all those numbers and divide by 6 will get you 78
The slope, y-intercept and the equation of the following graph are as follows:
1(a)
slope : 1
y-intercept: 2
Equation: y = x + 2
(b)
slope : - 1 / 3
y-intercept: - 1
Equation: y = - 1 / 3x - 1
2.
(a)
slope : 3 / 4
y-intercept: 5 / 4
Equation: y = 3 / 4 x + 5 / 4
(b)
slope : - 3 / 2
y-intercept: 1 / 2
Equation: y = - 3 / 2 x + 1 / 2

<h3>Slope intercept equation</h3>
where
m = slope
b = y-intercept
Therefore lets find the slope, y-intercept and equation of the following graph.
1.
(a)
(0, 2)(1, 3)
m = 3 - 2 / 1 - 0 = 1
b = 2
y = x + 2
(b)
(0, -1)(-3, 0)
m = 0 + 1 / -3 - 0 = - 1 / 3
b = -1
y = - 1 / 3x - 1
2.
(a)
(1, 2)(-3, -1)
m = -1 - 2 / -3 - 1 = 3 / 4
2 = 3 / 4 (1) + b
b = 2 - 3 / 4 = 5 / 4
y = 3 / 4 x + 5 / 4
3.
(b)
(-3, 5)(1, -1)
m = - 1 - 5 / 1 + 3 = - 6 / 4 = - 3 / 2
-1 = - 3 /2 (1) + b
b = -1 + 3 / 2 = 1 /2
y = - 3 / 2 x + 1 / 2
