a straight horizontal line is 180 degrees

box in the middle means that angle is 90 degrees

(s+1) + 90 + (2s-1) = 180

3s + 90 = 180

s = 30

What is the slope of a line perpendicular to a line that's passes through (3,8) and (1,-4)?

Serjik [45]

Answer:

-1/6

Step-by-step explanation:

First find the slope of the line through the points

m = (y2-y1)/(x2-x1)

= (-4-8)/(1-3)

= -12/-2

Now we need to find the slope of the line that is perpendicular

Perpendicular lines multiply to -1

6 * mp = -1

mp = -1/6

What is this? Please answer with an explanation

Dima020 [189]

Answer:

Slope = -2

Step-by-step explanation:

Since, slope = $\frac{\text{Rise}}{\text{Run}}$

Rise = -(y-intercept)

Run = (x-intercept)

From the graph attached,

y - intercept = -(4) = -4

x - intercept = 2

Therefore, slope the line given in the graph attached will be,

Slope = $\frac{-4}{2}$ = -2

Slope = -2
