Which of the following relations is a function? {(2, –3), (–3, 2), (2, 3), (–2, 3)}

{(–7, 6), (6, –7), (–7, 9), (10, 3)}

{(8, –5), (–5, 8), (–5, –8), (–8, 5)}

{(5, –4), (–4, 5), (–5, 4), (4, –5)}

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
