Ernie calculated the slope between two pairs of points. he found that the slope between ( ( -1, 4) 1 , 4 ) and (0, 0) ( 0 , 0 ) is -4 4 . he also found that the slope between (2, 7) ( 2 , 7 ) and (3, 3) ( 3 , 3 ) is -4 4 . ernie concluded that all of these points are on the same line. use the drop-down menus to complete the statements about ernie's conclusion.

His conclusion was incorrect.

Step-by-step explanation:

Since, slope of a line passes through and is,

Thus, the slope between (-1, 4) and (0, 0),

Also, the slope between (2, 7) and (3, 3),

Now,

There are two cases possible,

Case 1 : line passes through (-1, 4) and (0, 0) is parallel to line passes through (2, 7) and (3, 3)

Case 2 : (-1, 4), (0, 0), (2, 7) and (3, 3) are on the same line

Hence, we can not say that they are on same line only after getting same slope.

i.e. his conclusion was incorrect.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

central angle of a triangle has the same measure as its intercepted arc.
