Answer:

Vertical angles = 81 degrees

Angle (4y-1) = 99 degrees

Linear pair = 81 + 99 = 180 degrees

Step-by-step explanation:

2x + 5 = 3x - 33 (vertical angles)

33+5 = 3x - 2x

38 = x

3(38) - 33 = 81 degrees

4y - 1 + 81 = 180 (linear pair angles)

4y = 180 - 80

y = 100/4

y = 25

4(25) -1 = 99 degrees

What is the slope of the line through (-1,8) and (3,-4)?

laila [671]

Hey there!!

How do we find slopes ?

Slope = $\frac{y2-y1}{x2-x1}$

We are given with two co-ordinates :

(-1,8) and (3,-4)

Hence, the slope is :

$\frac{-4-8}{3+1}$

... $\frac{-12}{4}$ = -3

The slope is -3.

Hope my answer helps!
