Find the equation of the line perpendicular to y = - 2x + 3 that passes through the
point (4,9).

y=1/2x+7

Step-by-step explanation:

New slope is 1/2, so we need to plug in the coordinates to find b.

y=1/2x+b

9=1/2(4)+b

9=2+b

7=b

y=1/2x+7

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
