What is the area of this triangle? ( Please list steps used to find it also!!) The points are -3,0 3,0 0,5

15.

Step-by-step explanation:

Count the number of units across and above. You can utilize the distance formula or you can simply just count (since the coordinates aren't in decimals).

You get 6 across and 5 above so you want to multiply them as if you're finding the area of a rectangle. You get 30.

Now halve that to get the area of a triangle which is 15.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
