Question

Which equation represents the line through (4, -6) (0, 2)

Answer 1

y = -2x +2 I think

Explanation:

Answer 2

`y=-2x+2`

Explanation:

• Firstly we need to find the gradient
• We can do this with
  `(\triangle y)/(\triangle x)` (
  `(change\ in\ y)/(change\ in\ x)`)
• 
  `(2--6)/(0-4)`
• 
  `(8)/(-4)=-2`
• So far we have
  `y=-2x+c`
• Choose one of the pairs of coordinates
• I’ll choose (0,2)
• 
  `2=c`
• So your equation is
  `y=-2x+2`
