The graph of a proportional relationship contains the point (-30, 18)
Elena L [17]

Answer:

k=-\frac{3}{5}

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

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

we have the point (-30,18)

so

x=-30, y=18

Find the value of k

k=\frac{y}{x}

substitute

k=\frac{18}{-30}

Simplify

Divide by 6 both numerator and denominator

k=-\frac{3}{5}
