Jordan is calculating the slope of the trend line in the scatterplot below.
how can jordan use the plot to check the reasonableness of his answer?
his slope should be positive because the coordinates of all the plotted points are positive.
his slope should be positive because the trend line is slanted up to the right.
his slope should be negative because there are plotted points not on the line.
his slope should be negative because the x-coordinate of each plotted point is less than the y-coordinate.

The answer is B. His slope should be positive because the trend line is slanted up to the right.

Step-by-step explanation:

This answer is correct because the thred line is slanted up to the right, so it makes it positive. "His slope should be positive because the coordinates of all the plotted points are positive." is wrong because all the coordinates plotted positive isn't a valid reason. The other answers are wrong because the slope is positive.

B

His slope should be positive because the trend line is slanted up to the right.

Step-by-step explanation:

from left to right the line is increasing upward so it is positive so this means both of the bottom answers are wrong. answer A. is wrong because even slopes that are negative have all points positive sometimes so this is not a valid reason. therefore this leaves us with the answer B, which is correct.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
