The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5

8v - 4(v + 8) = 8

• 2

• 10

• 4

Write the equation of the graph in slope-intercept form

Use the graphs of f and g to describe the transformation from the graph of f to the graph of g.

• Graph g is reflected and steeper by a factor of 3

• Graph g is steeper by a factor of 3

• Graph g is reflected and less steep by a factor of 3

• Graph g is less steep by a factor of 3

8z - 22 = 3(2z - 4)

Hint: Graph each side of the equation.

Find the intersection point.

Since the original equation only contains one variable, we only need the x value.

If the blue graph is f(x) = x² then the red must be...

• g(x) = x² - 5

• g(x) = x² + 5

• g(x) = (x - 5)²

• g(x) = (x + 5)²
