I don't understand how to do this, could I have some help?​
kondaur [170]

Step-by-step explanation:

step 1. slope = rise/run

step 2. the rise is the height between any 2 points

step 3. the run is the distance left or right between the same 2 points

step 4. if the line goes up "left to right" the slope is positive, down it is negative

step 5. slope = + 6/2 = 3.

This question<br>find the value of x y and z​
Klio2033 [76]

Answer:

x = 6

y = 24

z = there is no z?

Step-by-step explanation:

All angles of a polygon add up to 360 degrees

The 2 parellel lines on top and bottom mean that there are 2 right angles on the left side

3y + 18 = 90

3y = 72

y = 24

15x + 30 + 10x = 180

25x = 150

x = 6
