Find the value of k if it is known that the graph of y=kx goes through: b(−30, 3) need quickshow work

The value of k if it is known that the graph of y=kx goes through B(−30, 3) is -0.1.

Linear equation

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Given the point B(-30, 3), hence:

3 = -30k

k = -0.1

y = -0.1x

The value of k if it is known that the graph of y=kx goes through B(−30, 3) is -0.1.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
