One equation in a linear systemis x+2y=4. Write another equation so that the system has the unique solution (-2,3)

Question

anonymous · Answer

easiest way would be to find the line perpendicular to this line

anonymous · Answer

as you know lines that are perpendicular cross at one specific point at 90 degrees

anonymous · Answer

solve your equation for y should get you

2y=4-x

y=2+(-1/2)x

anonymous · Answer

which is equal to (-1/2)x+2

anonymous · Answer

in order for a line to be orthogonal or perpendicular to this other line, the slope must be the opposite reciprocal of the slope you have

anonymous · Answer
