These look like displacement/distance questions

A. (DISTANCE) If Teddy went 8 feet underwater and 8 back to the surface he swam a total of 16 feet.

B. (DISPLACEMENT) They are looking at the final position compared to the initial position for this one. If you go 1.5 miles west and then 1.5 miles east, you're right back to where you started. So 0 miles away from the house. They do not want total distance travelled they want displacement.

C. (DISTANCE) You start at -50 feet (vertically, compared to sea level I'm guessing) and end up at 50 feet above vertically so you travelled a distance of 100 feet.

D. (DISTANCE) The change from -3 degrees to 3 degrees is 6 degrees.

What is the equation of a line that passes through the point (8,1) and is perpendicular to the line whose equation is y= -2/3 x
Alik [6]

Answer:

The equation of this line would be y = 3/2x - 11, which is the answer D.

Step-by-step explanation:

In order to find this equation we must first find the slope of the original line. The original slope (the coefficient of x) is -2/3, which means the new slope will also be 3/2 because perpendicular lines have opposite and reciprocal slopes. Now, we can use this slope along with the point in point-slope form to find the equation of the line.

y - y1 = m(x - x1)

y - 1 = 3/2(x - 8)

y - 1 = 3/2x - 12

y = 3/2x - 11
