Question

(Algebra II) Extra points!!Determine whether y varies directly with x
If so, find the constant of variation k and write the equation.(image attached)
Please explain if you can. Please help! Giving brainliest! Everything helps TIA

Answer 1

Answer:

• k = 1.6
• y = 1.6x

Step-by-step explanation:

If the variation is proportional dividing the y-value by the x-value will give the same result for all table entries. That quotient is the constant of variation (k).

Here 6.4/4 = 11.2/7 = 16/10 = 20.8/13 = 1.6

The value of y varies directly as x, and the constant of variation is 1.6. The equation is ...

  y = 1.6x
