Line c passes through points (1, 14) and (7, 7). Line d is perpendicular to c. What is the slope of line d?

anyanavicka [17]

Answer:

6/7

Step-by-step explanation:

Your first step will be to find the slope of Line C. Using the slope formula of $\frac{y_{2}-y_1 }{x_2-x_1}$ , the slope of Line C is $\frac{7-14}{7-1} = \frac{-7}{6}$ .

If Line D is perpendicular to C, that means the slope is the negative reciprocal of Line C. So, that means the slope is 6/7.

What is the slope of the line that passes through the following points? <br> (-1,-2) and (-3,-4)

iragen [17]

Answer:

y = x - 1

Step-by-step explanation:

Find the slope:

(-4 - (-2))/(-3 - (-1))

-2/-2 = 1

y = x + b

Plug in one of the points:

(-1,-2)

-2 = -1 + b

b = -1

y = x - 1
