Given the point (0,5) and a slope of 7, write an equation in point-slope form

• y - 0 = 7(x - 5)

• y - 5 = 7(x - 0)

• y - 7 = 5(x - 0)

• y - 5 = 0(x - 7)

Put this into standard form:
y = 3x + 2

• y + 3x = 2
• 3x + y = 2
• -3x + y = 2
• 3x - 2y = 2

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)

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)

Write the following in standard form:
y = -3x - 6

• x + 3y = 6
• 3x + y = -6
• 12x + 3y = -1
• 5x - y = 4

Write the following linear equation in standard form. 
y=-2x+3

• 2x-y=3
• y-3=-2x
• 2x+y=3
• xy-2=3x

Write the following equation in STANDARD form:
y = -4x + 7

• 4x + y = -7
• y - 7 = -4x
• -4x + y = 7
• 4x + y = 7
