A = 25 units²

Step-by-step explanation:

First, figure out where the lines intersect.

Let's start with x = 0 and y = x:

because x = 0, substitute x in y = x    

    y = 0 so the intersection point of these two lines is (0,0)

With, x + y = 10 (or y = 10 - x) and x = 0:

  substitute x again y = 10 - 0, so y = 10 and the intersection point is (0,10)

The last point has to be found by setting y = x and x + y = 10 (y = 10 - x) equal to each other: x = 10 - x

solve for x: x = 10 - x

                  2x = 10

                    x = 5

find y: y = 10 - 5

          y = 5 and the intersection point is (5,5)

Now that you have the vertices of the triangle, you can find the area. (0,0) and (0,10) are on the y-axis and has a length of 10 units; this is your base. To find the height, you need to picture the triangle on the coordinate plane. Point (5,5) lines up with the midpoint (0,5) of the side with (0,0) and (0,10). From this, you can see that the height is  5 units.

Use the triangle area formula: A = 0.5bh

A = 0.5(10)(5)

  = 0.5 × 50

A = 25 units²

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?
