Question

a path across a park is represented by the equation y=-2x+5. A new path will be built perpendicular to this path. the two paths cross at (-2,9). I identify the equation that represents the new path. ​

Answer 1

y = ½x + 10

Explanation:

Perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE Rate of Changes [Slopes], so you need to have a slope of ½, like in the work shown below:

9 = ½[-2] + b

-1

10 = b
