Find k, the constant of proportionality, for the data in this table. Then write an equation for the relationship.
VashaNatasha [74]

Answer:

k=\frac{32}{5},  y=\frac{32}{5}x

k=6.4, y=6.4x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

Find the value of the constant of proportionality k

take any ordered pair from the data

For x=25, y=160

k=\frac{y}{x}

substitute the values of x and y

k=\frac{160}{25}

simplify

k=\frac{32}{5}

The linear equation is equal to

y=\frac{32}{5}x

or

y=6.4x

Please help asap calculate the slope of the line through the points (6,-8) and (3,-4).
sammy [17]

Answer: y = -4/3x + 0. Yes, that point lies on the line

Step-by-step explanation:

Use this equation, Δy/Δx and this one, y = mx + b. Or, change in the y value divided by the change in the x value.

-4 + 8 = 4

3 - 6 = -3

The slope, m, is -4/3. Now solve for b by plugging in the slope.

-4 = \frac{-4}3 (3) + b. B is equal to 0

To see if that point lies on the function, plug it in the equation and see if it is true. Multiply -4 x -3 to get 12, divide by 3 to get 4, then add 0. The equation says that 4 = 4, which is infact true
