Question

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

Answer 1

Answer:

y = -2x +2 I think

Step-by-step explanation:

Answer 2

Answer:

$y=-2x+2$

Step-by-step explanation:

• Firstly we need to find the gradient
• We can do this with $\frac{\triangle y}{\triangle x}$ ($\frac{change\ in\ y}{change\ in\ x}$)
• $\frac{2--6}{0-4}$
• $\frac{8}{-4}=-2$
• 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 $y=-2x+2$
