Question

The path of an aeroplane is given by the equation 3x – 4y = 1 2: Represent the path

graphically. Also, show that the point (-4,-6) lies on the graph. Just give the full steps also pls

Answer 1

Graph is attached

Explanation:

The equation of the line is 3x - 4y = 12

If the point(-4, -6) is to lie on this line then the values x = -4 and y = -6 must satisfy this equation

Plug in these values on the left side
3(-4) - 4(-6) = -12 - (-24) = -12 + 24 = 12

So indeed this point satisfies this equation and therefore it must lie on this line
