CPM Homework Help : CAAC Problem 6-12

Juan thinks that the graph of 6y + 12x = 4 is a line. Homework Help ✎
1. Solve Juan's equation for y.
2. Is this equation linear? That is, is its graph a line? Explain how you know.
3. What are the growth factor and y-intercept of this graph?

Hint (a):

Get y by itself by subtracting 12x from both sides.

Answer (a):

$y= -2x + \frac{2}{3}$

More Help (a):

6y + 12x = 4
−12x −12x
6y = 4 − 12x

Hint (b):

Can it be written in the form y = mx + b?

Hint (c)

What is m in this equation? What is b?
