The equation of line that passes through point (-3, 8) and has an undefined slope is x = -3
<u>Solution:</u>
Given that we have to find the equation of line that passes through point (-3, 8) and has an undefined slope
Since the line has an undefined slope. This informs us that it is a vertical line parallel to the y-axis and passing through all points in the plane with the same x-coordinate.
If the slope of the line is undefined, then, by definition the line is a vertical line.
For a vertical line, the value of  x  is the same for each and every value of  y
Given point is (x, y) = (-3 , 8)
Because the value of  x  in the point provided in the problem is -3, we get
Equation of line is : x = -3
 
        
             
        
        
        
Let's make an equation where x is the number of gallons and y will be the overall price.
2.5x=y; since it is $2.52 PER gallon, you need to multiply the amount of gallons by the cost. In this case, it is 4.
2.5(4)=10
So, the price of 4 gallons is $10.
 
        
                    
             
        
        
        
Answer:
The discounted price would then be 18 dollars.
Step-by-step explanation:
Start by taking the original price which was 45 and multiply that by .40 (the discount) you should  get a total of 18.
