What is y when x = 1?
Answers
Answer:
y = 380
Step-by-step explanation:
Pick any two points in table to find slope, let's use (4, 350) and (6, 330):
m = (y₂ - y₁) / (x₂ - x₁)
= (330 - 350) / (6 - 4)
= -20 / 2
m = -10
Pick any one point in table, let's use (4, 350) and slope m from above to find y-intercept:
y = mx + b
350 = -10(4) + b
350 = -40 + b
b = 390
Use m and b from above to form Equation of line:
y = mx + b
y = -10x + 390
Pick a few points from table to check equation y = -10x + 390 is valid:
Point (4, 350)
350 = -10(4) + 390
350 = -40 + 390
350 = 350
Point (8, 310)
310 = -10(8) + 390
310 = -80 + 390
310 = 310
What is y when x = 1:
y = -10x + 390
y = -10(1) + 390
y = -10 + 390
y = 380

Sanjay created a scatter plot of the relationship between the number of times he visited different coffee shops each month, y, and the distance in miles of the shops from his home, x. He calculated the equation of the trend line to be y=−2.25x+30. Use this information to predict the number of times in one month Sanjay would visit a coffee shop that is 8 miles from his home.

Each point label on the box plot should be matched to its description as follows;
Point A ↔ minimum value.
Point B ↔ first quartile.
Point C ↔ median.
Point D ↔ maximum value.
What is a box-and-whisker plot?
In Mathematics and Statistics, a box plot is a type of chart that can be used to graphically or visually represent the five-number summary of a data set with respect to locality, skewness, and spread.
Based on the information provided about the data set, the five-number summary for the given data set include the following:
- Minimum (Min) is labelled point A = 4.
- First quartile (Q₁) is labelled point B = 8.
- Median (Med) is labelled point C = 12.
- Third quartile (Q₃) = 14.
- Maximum (Max) is labelled point D = 20.

B is the first quartile
The point with the line through it (next to C) is the median.
The point to the outside of the box is the third quartile.
D is the maximum value.
