ANSWER
EXPLANATION
Since the parabola has the (0, 0) and the directrix at y=2.
The equation is of the form
where (h,k) is the vertex.
The vertex is half way between the directrix and the focus.
The vertex will be at (0,1)
and is the distance from the vertex to the focus which is 1.
Answer:
It will be in the attachment below.
Step-by-step explanation:
Translating a vertex 3 units down and 4 units to the left means that the x coordinate is 4 less than before and the y is 3 less. So, subtract 4 from -5 to get -9; from -2 (twice) to get -6 (twice), and subtract 3 from 5 (twice) to get 2 (twice); from 3 to get 0. So, the new coordinates are (-9, 2), (-6, 2), and (-6, 0). The original shape is in red, and the translated shape is blue.
Step-by-step explanation:
We have been given that Jeanie stated that the equation of this line best fit for the scatter plot is .
Let us find the slope of the line of best fit using points (2,7) and (4,6) in slope formula.
We can see that slope of line of best fit is .
Since the equation of a line written in slope-intercept is in form: , where m=slope of line, b= y-intercept.
Upon substituting m= and coordinates of one point in slope-intercept form of equation we will get,
Upon substituting m= and b=8 in slope intercept form, we will get,
We can see that equation of the line of best fit is . Jeanie got 1/2 as slope of the line of best fit, which is wrong, therefore, Jeanie's equation of the line of best fit is not correct.
