Answer:
y - 10 = 2(x - 4)
Step-by-step explanation:
Recall this: The slope of a new line perpendicular to a given line is the negative reciprocal of the slope of the given line.
Thus: The slope of the new line is the negative reciprocal of (-1/2), or +2.
Using the point-slope formula for the equation of a line,
y - k = m(x - h)
becomes
y - 10 = 2(x - 4)
This could also be written as y = 2x - 8 + 10, or y = 2x + 2
