For the equation
y - 3 = 2(x + 4),
which of the following is true?

• The line has m = 2 passing through the point (4, -3)

• The line has m = 2 passing through the point (3, -4)

• The line has m = 2 passing through the point (-4, 3)

• The line has m = 2 passing through the point (-3, 4)

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)

• y - 4 = -1/4(x + 7)

• y + 7 = 4(x - 4)

• y - 7 = -1/4(x - 4)

What is the equation for the line with a slope of 7 and passes through (0,1)?

• y = -7x + 1

• y = 7x + 1

• y = -1/7x - 1

• y = -1/7x + 1

What is the equation of a line parallel to the following line that passes through the given point? 
y = -4x + 6      (2, -1)

• y = 1/4x + 6

• y = -4x + 7

• y = -4x + 2

• y = 1/4x -1 

What is the slope intercept form of this equation? 
3x - 4y = 24

• y = 3/4 x + 6

• y = 3/4 x - 6

• y = -3/4x + 6

• y = -3/4x - 6

• y = 1/3x + 8/3

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)
