What is the y intercept of the linear equation x
spin [16.1K]

x isn't a linear equation, it's just a variable or an expression or a letter of the alphabet.

x = 0 is a linear equation and is a line in the Cartesian plane. In fact, it's the y axis itself.

So every point on the line x=0 is a y intercept.

There is no "the" y intercept, no unique y intercept.

9/15   divided by 27/30 =
Tema [17]

When dividing two fractions, we flip the second fraction and multiply by it (that is, use the reciprocal).

\frac{9}{15} ÷ \frac{27}{30}

= \frac{9}{15} × \frac{30}{27}

You can either multiply top by top and bottom by bottom or you can simplify by dividing out common factors.

= \frac{1}{1} × \frac{2}{3}

= \frac{2}{3}
