Answer:

Step-by-step explanation:

Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{-6-9}{2-4}=\dfrac{-15}{-2}=\dfrac{15}{2}\\\\

Equation:

y -y_{1}=m(x -x{1})\\\\y - 9 = \dfrac{15}{2}(x-4)\\Multiply \ the \ entire \ equation \ by 2\\\\2*(y -9)=2*\dfrac{15}{2}(x-4)

2y - 2*9 = 15(x - 4)

2y - 18 = 15x - 60

2y - 18 + 60 = 15x  

2y + 42 = 15x

15x - 2y = 42

Adrian purchases six tubes of paint and three paint brushes at a craft store each tube of paint cost $2.50 each paint brush cost
lesantik [10]

Answer:

The total amount of money pays by Adrian is $14.5 .

Step-by-step explanation:

As given

Adrian purchases six tubes of paint and three paint brushes at a craft store.

Each tube of paint cost $2.50 each paint brush cost $0.50 .

Total cost of the 6 tubes of paints and 3 paint brushes = 6 × Cost of each tube of paint + 3 × Cost of each paint brush cost .

Putting the values in the above

Total cost of the 6 tubes of paints and 3 paint brushes = 6 × 2.50 + 0.50 × 3

                                                                                           = 15 + 1.5

                                                                                           = $16.5

As given

Adrian has a coupon for $2 of his purchase .

Total amount money pay by Adrian = Total cost of the 6 tubes of paints and 3 paint brushes - Coupon cost

Putting the values in the above

                                                            = $16.5 - $2

                                                            = $ 14.5

Therefore the total amount of money pays by Adrian is $14.5 .
