Question

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

Answer 1

Answer:

D. y = -4x - 6

Step-by-step explanation:

→ Work out gradient of line

$\frac{2-6}{-2--3} =\frac{-4}{1} =-4$

→ 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
