ExtremeBDS [4]
Hi there! The answer is 9 square units

To find the area of a triangle we use the following formula:
Area = 0.5 * base * height.

The base of this triangle:
AC = 6 

The height of this triangle:
BD = 3

Filling in this formula gives us: 
Area = 0.5 * 3 * 6 = 9

Therefore, the answer is 9 square units

Write an equation for the line containing (7,7) and (2,-3).
drek231 [11]

Answer:

y = 2x - 7

Step-by-step explanation:

To find the line equation we assume that its form is y = m*x + b. Where m is the slope and b is the independent variable that intercepts the Y axis.

If we have two points as P1=(x1,y1) and P2=(x2,y2) we can use the slope formula as:

m = (y2-y1)/(x2-x1)

The points given are P1=(7,7) and P2=(2,-3), then the using the slope formula we obtain:

m = (-3-7)/(2-7)

m = (-10)/(-5)

m = 2

By now the equation is y = 2x + b. To find the value of b we have to replace in the equation any point, in this case i am using P2:

-3 = 2*(2) + b

-3 = 4 + b

-3 -4 = b

-7 = b

Therefore the equation of the line is:

y = 2x - 7
