Answer:
slope = 3
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
= - 
Given m = -
, then
= -
= 3
Answer:
62°
Step-by-step explanation:
Given that the triangle has two angle measures of 41° and 77°.
All the angles in a triangle must add up to 180° (e.g. 20° + 60° + 100°). So we write a simple equation to solve for the mystery angle measure:
Let x = the missing measure

Now that we have our equation, let's start solving it. First, we need to add 41 and 77 together which simplifies the equation: 
Then we subtract 118 from both sides to isolate x - this will give us the value of this variable: 
Therefore, the third angle must have a measure of 62°.

Step-by-step explanation:

Answer:
-3/2.
Step-by-step explanation:
When x is 4 , y is 9. When x is 8, y is 3. Therefore, you do the change in y/change in x to find the average rate. 3-9/8-4. This is equal to -3/2.
