We can use the slope formula: 

By plugging the values into this formula, we can solve for the slope.
-1 - 4 / -8 - 0
-5 / -8
Because there are two negatives, they cancel out;
The slope is 5/8
 
        
             
        
        
        
23x and 9x are alike terms so
23x-9x
14x
        
             
        
        
        
Answer:
We have the problem:
"Clare is in charge of getting snacks for a road trip with her friends and her dog. She has
$35 to go to the store to get some supplies. The snacks for herself and her friends cost
$3.25 each, and her dog's snacks costs $9 each."
In this situation we have two variables:
X =  number of snacks for herself and her friends that she buys. Each one of these costs $3.50
Y = number of snacks for her dog that she buys. Each one of these costs $9.
The total cost, in this case, can be written as:
X*$3.50 + Y*$9
And we know that she has $35 to spend, so she can spend $35 or less in the store, then we have the inequality:
X*$3.50 + Y*$9  ≤ $35
Where we defined all the quantities in the inequality.
 
        
             
        
        
        
the answer is circle idk if it's right but it could be I'm in high school I've been through algebra 1 now in geometry
