Question

Write the equation 4x + 2y = 5 in the form y = mx + b.

y equals two x plus start fraction five over two end fraction
y = 2x + 5
y equals minus two x plus start fraction five over two end fraction
y equals minus two x minus start fraction five over two end fraction

Answer 1

Option- y equals minus two x plus start fraction five over two end fraction is correct. That is
`y=-2x+(5)/(2)`

Explanation:

Given equation is 4x+2y=5

We have to write the given equation in the form of y=mx+b

4x+2y=5

2y=5-4x

`y=(5-4x)/(2)`

`y=(5)/(2)-(4x)/(2)`

`y=(5)/(2)-2x`

Rewritting the above equation as below

`y=-2x+(5)/(2)`

Therefore the given equation can be written in the form
`y=-2x+(5)/(2)`

Option- y equals minus two x plus start fraction five over two end fraction is correct. That is
`y=-2x+(5)/(2)`.
