Exercise 16 Page 159

Can the equation be written in standard form?

No.

Practice makes perfect

If the given equation is a linear equation, it will follow the standard form. Ax+ By=CIn this form, A, B, and C are constants and A and B cannot both be zero.

4y^2 +9 = -4

LHS-9=RHS-9

4y^2=-4 -9

Subtract term

4y^2=-13

Since there is no x-term, A is equal 0 in the standard form. Writing the given equation this way, we see that something is different. 0x+ 4 y^2=-13 The y-term has an exponent. Because of this, the equation cannot be written in standard form and is not linear.
