Question

Suppose x can be expressed as a function of y by x = 5y − 3.
a. How can y be expressed as a function of x?
b. What is the relationship between the slopes of the two linear equations?
c. How do the x-intercepts and y-intercepts of the two equations relate?

Answer 1

a)
x = 5y − 3
5y = x+3
y = (1/5)x + 3/5

b) the slope is 1/5, they are the same equation

c) they are the same equation
