Step-by-step explanation:
let x= cost of 1 book
i’m pretty sure that’s it

Answer:
y - intercept = 0
Slope of line = 2.86
Step-by-step explanation:
THE y-intercept is the point on the y - axis where the line crosses the y - axis. The y-intercept of the graph is 0.
The slope of the line is the ratio of change in the y-axis to the x - axis.
Gradient / slope = Δy / Δx = (y2 - y1) / (x2 - x1)
Drawing a right angle triangle at any point on to meet the line of best fit :
y2 = 35, y1 = 15, x2 = 12, x1 = 5
Slope = (y2 - y1) / (x2 - x1) = (35 - 15) / (12 - 5)
Slope = 20 / 7 = 2.857
Slope = 2.86
Where’s the answer choices ?!
If I remember correctly, more is the middle. So you first line up the numbers from least to greatest-
25,20,20,20,22
Then you count equally from each side to get to the number in the middle.
The answer would be 20
For future references, if there are two numbers in the middle, you and them together, and then divide that number by two.
Hope this helps!
38b + 61t = 791.50....multiply by 27
54b + 50t = 923.....multiply by -19
-------------------
1026b + 1647t = 21370.5 (result of multiplying by 27)
-1026b - 950t = - 17537 (result of multiplying by -19)
------------------add
697t = 3833.50
t = 3833.50 / 697
t = 5.50 <=== cost of each towel
38b + 61t = 791.50
38b + 61(5.50) = 791.50
38b + 335.50 = 791.50
38b = 791.50 - 335.50
38b = 456
b = 456/38
b = 12 <== cost of each bed sheet
so the cost of 1 towel and 1 bed sheet is : 12 + 5.50 = 17.50
