Question

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

Answer 1

Answer:

(-3,-5)

Step-by-step 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.

Answer 2

Answer:

m =5/3

Step-by-step explanation:

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