Question

Line d passes through points (10, 10) and (7, 5). Line e is perpendicular to d. What is the slope of line e?

Simplify your answer and write it as a proper fraction, improper fraction, or integer.

Answer 1

m =5/3

Explanation:

`\mathrm{Slope}=(y_2-y_1)/(x_2-x_1)\\\\\left(x_1,\:y_1\right)=\left(10,\:10\right),\\\:\left(x_2,\:y_2\right)=\left(7,\:5\right)\\\\m=(5-10)/(7-10)\\\\Simplify\\\\m = (-5)/(-3) \\\\m=(5)/(3)`

Answer 2

(-3,-5)

Explanation:

subtract y1 from y2 and you get -5. Now subtract x1 from x2 and you get -3. Now put the x value first and then the y value.
