Area of triangle with following verticies (0,-9), (3,-9), and (0,-2)

Neporo4naja [7]

Answer:

Area = 21/2 = 10.5 area units

Step-by-step explanation:

Two of the points are on the same line (the y-axis) as they both have x-coordinates of 0. This can thus be the base of your triangle.

Two more are on the same line (y= -9) as they both have the same y-coordinate of -9. This can be the height of your triangle.

So you have a base which is between -2 and -9 (7 units) and a height which is between 0 and 3 (3 units) so now just use the equation for area of a triangle $A=0.5*b*h$

Answer:

The option A and C are correct that is

$-3(x - 8)\\\ \frac{3}{2}(-2x +16)$

$-3x + 24 \\ \textrm {is quivalent to}\\-3(x - 8) = -3x --3\times8 = -3x + 24\\\\\frac{3}{2}(-2x + 16) = \frac{3}{2}\times-2x + \frac{3}{2}\times 16 = -3x + 24$

Therefore, The option A and C are correct that is

$-3(x - 8)\\\ \frac{3}{2}(-2x +16)$
