Write in slope intercept form
5x - 3y = -9

• y = (5/3)x - 3

• y = (5/3)x + 9

• y = (5/3)x + 3

• y = (3/5)x + 3

Johnny has to pay $15 for a large pizza and 1.50 for each topping.  What is the meaning of the y-intercept?

Write in standard form.
2x - 2 = 6y

• 2x - 6y = 2

• 2x + 6y = 2

• 2x + 6y = -2

• 2x - 6y = -2

For the equation
y - 3 = 2(x + 4),
the line has a slope of 2 and contains what point?

• (-4, 3)

• (3, -4)

• (-3, -4)

• (-4, -3)

For the equation
y + 1 = -3(x - 5),
the line contains the point (5, -1) and has a slope of?

• -1

• 1

• -3

• 5

Write the equation in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

• y + 1 = -3(x - 2)

• y + 1 = -3(x + 2)

• y - 1 = 3(x - 1)

• y + 2 = -3(x + 1)

What type of slope?

• undefined

• positive slope

• negative slope

• zero slope
