The equation below describes a proportional relationship between x and y. What is the constant of proportionality? The constant of proportionality y=3/5x

45

step-by-step explanation:

160 cm

step-by-step explanation:

you have to add all the sides together

is there more info provided? there is not enough information given in the problem

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
