That triangle has a horizontal base with y=2. The length of that base is RS=1-(-4)=1+4=5. The height of the triangle is the vertical distance from line y=2 to T(-5,-4). That height is 2-(-4)=2+4=6. The area of the triangle is base * height/2 = 5*6/2= 15
The answer is 15 units ^2
Answer: y=x
The slope of the perpendicular line is the opposite reciprocal. So you do -(-1/1) which equals 1. So now we have y=x+b. Plug (3,3) into this and you get 3=3+b. So b=0 and the equation is y=x
Answer:yes, its correct
