Question

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

Answer 1

Hello from MrBillDoesMath!

Answer:

y = 2x + 2.5

Discussion:

2y -4x = 5                        => add 4x to both sides

2y - 4x + 4x = 4x + 5        => -4x + 4x = 0

2y = 4x + 5                      => divide both sides by 2

y = 2x + (5/2)                   => as 5/2 = 2.5

y = 2x + 2/5

Thank you,

MrB
