Question

Of maths, coordinate geometry please answer​

Answer 1

Answer:

2x + 9=0

2x = -9

x = -9/2

i) Draw a number line and then mark -9/2 on it

ii) Draw a cartesian plane and then y = any number and x will always be equal to -9/2. So you would get a line parallel to Y-axis passing through -9/2

hope this helps
