Is the sentence true or false?
The graph of the linear equation is always a straight line.
True
False
y=xy=\sqrt{x}y=x is a linear equation.
y=x2y=x^2y=x2 is a linear equation.
Which one is linear equation?
y=x+8y=x+8y=x+8
y=2x2+1y=2x^2+1y=2x2+1
y=x1/2+7y=x^{ }1/2+7y=x1/2+7
y=x2+1y=x^2+1y=x2+1
y=8x12+7y=8x^{\frac{1}{2}}+7y=8x21+7
y=27x+3y=27x+3y=27x+3
The general form of the equation of a straight line is ax+by+c=0ax+by+c=0ax+by+c=0
y=x12+4y=x^{\frac{1}{2}}+4y=x21+4
y=6xy=6xy=6x
y=−xy=-xy=−x
y=3y=3y=3
y=x12+7y=x^{\frac{1}{2}}+7y=x21+7
y=2x+1y=2x+1y=2x+1
It is done.
