A triangle in the xy-coordinate plane is formed by the points (−2,0), (4,0), and (1,5). What is the area of this triangle?
5 square units
9 square units
10 square units
15 square units

The answer is 15 sqr units.

Step-by-step explanation:

The formula of area of triangle is (BxH)/2. By folowing the coordinates given and the formula, our B=6, H=5. So... (BxH)/2 which is (6x5)/2 which is 30/2= 15 sqr. units.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
