Complete the point-slope equation of the line through (8,-8) and (9,8)
y-8=?

y-8=16(x-9)

Step-by-step explanation:

well find the slope and put it in y-y1 = m(x-x1)

slope = 16

since your given 1/2 of the equation fill in m as slope and x1 as you intercept

y-8 = 16(x-9)

its 4 because 2 times 2 is 4, if you double the number two you get four

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
