The table below shows the squares of different numbers:
gogolik [260]
The table in Part A represents y as a function of x. This means that the value of Y is dependent on the value of X. The table can be represented by an equation that describes the relation of X and Y:
y =  x^{2} or f(x) = x^{2}
By substituting any value of X, you get a specific value of Y based from the given relationship, thus Y is a function of X. 

For Part B, the value of f(150) is $470 and it represents the total cost for borrowing a rowboat for 150 hours. By substituting the value of x = 150 into the function, you get the total cost:
f(x) = 20 + 3x \\ where   \\ x = 150 \\ f(150) = 20 + 3(150) \\ f(150) =20 + 450 \\ f(150) = $ 470

Write the slope intercept form of the equation of the line through the given point with the given slope
liraira [26]

Answer:

y = -3/7 x + 41/7

Step-by-step explanation:

The Slope (m)  is -3/7

y= mx+ b

They y intercept passing through the  pt.  (-2,5 ) is

   5 = -3/7(2) +b

   5 = -6/7 +b

  b= 41/7

y = mx +b

y = -3/7 x + 41/7
