Answer:

A

Step-by-step explanation:

Remark

The trick here is convert what you have to Ax + By = C

Solution

Given

y - 3 = 1/2 ( x + 6)                        Multiply both sides by 2

Solve

  • 2(y - 3) = 2 * 1/2 (x + 6)               Do the multiplication
  • 2(y - 3) = x + 6                            Remove the brackets
  • 2y - 6 = x + 6                              Add 6 to both sides.
  • 2y - 6 + 6 = x + 6 + 6                  Combine
  • 2y = x + 12                                   Subtract x from both sides.
  • -x + 2y = x - x + 12                       Combine
  • -x + 2y = 12

Answer

  • A = - 1
  • B = 2
  • C = 12

or

  • When you multiply through by - 1 you get x - 2y = - 12 which is A

Find the equation of a straight line passing through the point (0,1) which is perpendicular to the line y=-2x+2

Answers

Answer:

y = (1)/(2) x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 2 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

m_(perpendicular) = - (1)/(m) = - (1)/(-2) = (1)/(2)

The line crosses the y- axis at (0, 1) ⇒ c = 1 , then

y = (1)/(2) x + 1 ← equation of perpendicular line
