Answer:
The equation of the line that has a slope of -2 and y-intercept of 1 will be:
- y = -2x+1
Step-by-step explanation:
The slope-intercept form of the line equation
where
- m is the slope
- b is the y-intercept
Given
The slope m = -2
y-intercept b = 1
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
It is already stated that the y-intercept = -1
It means at y = 1, x = 0
Thus, we have the point (0, 1)
Now using the slope-intercept form
y = mx+b
substituting m = -2 and b = 1
y = -2x + (1)
y = -2x+1
Therefore, the equation of the line that has a slope of -2 and y-intercept of 1 will be:
- y = -2x+1

Answer:
Girl's plot
Step-by-step explanation:
The exact question is as follows :
Given - The dot plots compare the number of raffle tickets sold by boys and girls during a school fund-raiser.
To find - Which plot has an outlier?
Proof -
The correct answer is - Girls
Reason -
Girls plot has an outlier because values way outside the majority of the data.
Definition of outlier -
A value that "lies outside" (is much smaller or larger than) most of the other values in a set of data.
Here in the Girl's plot we can see that, all the dots are close but there is one dot that is lies outside
But in Boy's plot all the dots are close to each other , no dot is lies outside to any other dots.
So,
The correct option is -
Girl's plot has an outlier.
