Based on the scatterplot,what is the best prediction for city mpg if the highway mpg is 40?
2 answers:
Answer:
<h2>B) 35.</h2>Step-by-step explanation:
We know that a scatter plot is used to study to variables and see if they have some dependent relation, which is shown with a straight line. So, our job is to find the straight line that includes the major number of given points.
To have the best prediction possible, we draw a line that best fits to all points included in the scatter plot, as the image attached shows. There you can observe that the best prediction for 40 highway mpg is 35, because the red line shows that it must be between 30 and 40.
Therefore, the answer that best fits is B) 35.

Answer:
Step-by-step explanation:
Answer:
The slope of the line given by the linear equation is -2
The slope of the line shown in the graph is -1
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
- m is the slope
- b is the y-intercept
The rule of the slope of a line is m = , where
- (x1, y1) and (x2, y2) are two points lie on the line
Let us use these rules to answer the question
∵ The linear equation is y = -2x + 7
→ By comparing it with the form of the linear equation above
∴ m = -2
∵ m is the slope of the line represented by the given equation
∴ The slope of the line given by the linear equation is -2
From the given figure
∵ The line passes through points (6, 0) and (0, 6)
∴ x1 = 6 and y1 = 0
∴ x2 = 0 and y2 = 6
→ Substitute them in the rule of the slope above to find it
∵ m =
∴ m = -1
∵ m is the slope of the line shown in the graph
∴ The slope of the line shown in the graph is -1
