Find the slope of the line that passes through the two points.<br> (12,-5) and (10,-4)
hichkok12 [17]

Given parameters:

First point  = (12, -5)

Second point  = (10, -4)

Unknown:

Slope of the line = ?

Slope is simply the vertical rise divided by the horizontal distance.

             Slope  = \frac{Rise }{horizontal distance}

Simply to find slope;

           Slope  = \frac{y_{2} - y_{1}  }{x_{2} - x_{1} }

First point  = (12, -5), x₁  = 12 and y₁  = -5

Second point  = (10, -4), x₂  = 10 and y₂  = -4

Input the parameters:

       Slope  =  \frac{-4 -(-5)}{10 - 12}

                  = \frac{-4 + 5}{-2}

                  = - \frac{1}{2}

The slope of the line is -\frac{1}{2}

e-lub [12.9K]

Answer: Answer choice D

Step-by-step explanation: The linear function is y = -5/3 + 5, which means that the slope is 5/3. The fact that the slope is ascending to the left also eliminates the first two choices.

the 90 members of a service Club had the opportunity to vote for a club officers on Tuesday or Wednesday 3/5 of the members vote
oee [108]
For this problem, it is really important to find who voted on Tuesday first.
90×(3/5)= 54 
54 people voted on Tuesday. Since the people who voted on Wednesday was 1/4 of the members who did not vote on Tuesday.
90-54=36×(1/4)=9
9 people voted on Wednesday. Now add Tuesday and Wednesday together to find the ones that didn't vote.
54+9=63;90-63=27
27 people did not vote at all.
