Question

Which of the following are equations for the line shown below? Check all that

apply.
(-3,6)
(-2,2)
5
O A. y-2=-4(x + 2)
U
B. y + 3 = -4(x-6)
O C. y-6 = -4(x + 3)
D. y=-4x-6

Answer 1

D. y = -4x - 6

Explanation:

→ Work out gradient of line

`(2-6)/(-2--3) =(-4)/(1) =-4`

→ Write into y = mx + c format

y = -4x + c

→ Substitute ( -2 , 2 ) into the equation to find c

2 = 8 + c

→ Minus 8 from both sides

-6 = c

→ Write full equation y = -4x - 6
