Just need help on this first one

Step-by-step explanation:

Since  x=0 is the equation of the y axis, a line parallel to this line is a vertical line.

In particular, vertical lines have the following type of equation:

x=k

where k is the value of the x coordinate of any of the points belonging to the line.

In this case, we want a vertical line that passes through a point with  x coordinate equal to -2 , so every other point belonging to this line must have this same coordinate, and the equation of the line is thus

x=-2

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
