Which students, if any, have correctly identified a base and its corresponding height? which ones have not? explain what is incorrect.
(explain)!

The Explanation is below .

Step-by-step explanation:

a. )

Raul is correct because Height should always be Perpendicular

and Raul has drawn Height 'h' Perpendicular to the corresponding Base 'b'.

b. )

Mark is incorrect because Height drawn is NOT Perpendicular.

c. )

Kiki is incorrect because the corresponding base is incorrect, Height drawn is correct that is Perpendicular.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
