Since there are no given triplets, none of them!
Using the equation below, select the ordered triple that correctly indicates where the plane cuts the x-axis.3x+4y+8z=12

There are infinitely many ordered pairs: each point on the straight line defined by the equation is an ordered pair that is a solution. One example is (0.5, 2.5)
There are 6 such triples.
Using the equation below, select the ordered triple that correctly indicates where the plane cuts the x-axis.3x+4y+8z=12
7x + 2y + 3z = 42At the z-axis, 'x' and 'y' are both zero.0 + 0 + 3z = 42z = 14The coordinates of the z-intercept (the 'ordered triple') are (0, 0, 14)
I am sorry but the question is incomplete. You have not mentioned the ordered pairs and the equation is incomplete as well.

The list of choices that accompanies the question is really short.2x + 3y + 6z = 54At the y-intercept, 'x' and 'z' are zero.3y = 54y = 18
x = 5 and y = 4
x = 2 and y = -4
3x
There are an infinite number of ordered pairs that satisfy the equation.
