I need to answer these questions ASAP! Will give brainiest and helpful! 8) Write the unit rate of $7.35 for 5 ¼
ounces.

9) Fresh grapes cost $ 15.70 for 5
pounds. What does 1-pound cost?

10) If the total cost (t) is $535 for 20
calculators (c). What would the
equation look like
and what is the constant of
proportionality (K)?

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

you can't solve x because it is 2 linear equation and you only have one equation
