Jordan models the data with the equation y=-1.5x + 121, where x represents the number of minutes spent watching television and y represents the number of minutes spent exercising
Jordan computed a correlation coefficient of -0.98 for the data. What does the coefficient mean in terms of the data he collected

Because -0.98 is negative, the correlation between the variables is weak.
Because -0.98 is negative, there is no correlation between the variables
Because -0.98 is close to -1, there is a positive correlation between the variables.
Because -0.98 is close to -1, there is a strong correlation between the variables.

only 10/60 isn't equivalent

hope this : )

it has the same slope and a different y-intercept

hope this : )

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
