Write an equation passing through (-6, 7) that is parallel to 5x + 2y = 10

On a piece of paper graph f(x)=5•(0.4)^x

Arianna is buying plants for her garden. she buys 15 flowering plants for $96. pink flowering plants sell for $8, and purple flowering plants sell for $5. how many pink flowering plants did arianna buy? i figured out the answer! the answer is 7. 8x +5y = 96 plug in 7 for x 8 (7) + 5y = 96 56 + 5y = 96 subtract 56 from both sides 5y/y = 40/5 y = 8 she bought 7 pink and 8 purple plants

1.based of the diagrams what is the the value of x? 2.how would you verify your answer for x
