Which linear fundamental represents the line given by the point-slope equation y+7 = 2/3 (x+6)?

The base of the pyramid is the triangle on the very bottom. The formula for the area of a triangle is A = 1/2 x base x height.

In this triangle, the base length is 6 cm and the height is 7 cm, as shown clearly in the image. Using the formula for the area, we can easily solve for the area of this triangle.

A = 1/2 x 6 x 7

A = 1/2 x 42

A = 21 cm^2

Hope this helps! :)
