Question

its asking me to explain the relationship between the constant rate between measures in a proportional relationship and the slope of a line which is the graph of the equation representing the proportional relationship

Answer 1

Constant rate between measures X,Y is

k = Y/X

Slope of a line y= mx + b is represented by

m = ( y- b) / x

THEN answer is

if b = 0 , both k and m are equal k=m

And if b≠ 0 then they have different values

That is the relationship between
