Question

Which is the equation of the graphed line written instandard form?1. y = x2. x - 1/2y = 03. x - y = 04. y = 1/2 x

Answer 1

for x = -3, y = -3

for x = 0, y = 0

for x = 2, ,y = 2

for x = 5, y = 5

therefore the equation is:

x = y

so in the standard form:

`\begin{gathered} Ax+By=C \\ \text{this is} \\ x=y \\ x-y=y-y \\ x-y=0 \end{gathered}`

answer: 3. x - y = 0
