Question

What is the standard form of Y=2/5x+2

Answer 1

bearing in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

$\bf y = \cfrac{2}{5}x+2\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{5}}{5(y)=5\left( \cfrac{2}{5}x+2 \right)}\implies 5y=2x+10 \\\\\\ -2x+5y=10\implies 2x-5y=-10$
