Question

Line x has a slope of -1/2. Line y is perpendicular to line x. What is the slope of line y?

Answer 1

`\huge\boxed{Hi\;there!}`

★Perpendicular lines have slopes that are opposite reciprocals.

This means we take a number, change its sign, and then, flop it over:

`\displaystyle-(1)/(2)`

`\displaystyle(1)/(2)`

`2`

`\huge\boxed{\mathfrak{Answer:{\boxed{the\;slope\;of\;line\;y\;is\;2}}}}}`

`\bold{Hope\;it\;helps!}`

`\rm{Enjoy\;your\;day!`

`\boxed{AmiableTeen:)}`

Answer 2

2

Explanation:

perpendicular means the opposite inverse of a slope. So -1/2 will become 2/1 or simply 2.

opposite means the sign will change, negative becomes positive and positive becomes negative.

inverse flip numerator and denominator.
