For the equation $5x + 3y = 90$,if $x = 12$,then $y = \dots$

If a linear equation has solutions $(-2, 2), (0, 0)$ and $(2, -2)$,then it is of the form

Draw the graph of the equation represented by a straight line which is parallel to the $x$-axis and at a distance of $3$ units below it.

In a Cartesian plane,the graph of $x=0$ is $\ldots \ldots \ldots$

"The price of a bat in a toy store is five times the price of a ball." Represent this statement as a linear equation in two variables.

Examine which of the following points are solutions of the equation $3x - 2y = 12$,and which are not:
$(1) (0, -6)$
$(2) (2, 3)$
$(3) (2, -3)$
$(4) (-4, 0)$
$(5) (-2, -9)$
$(6) (6, 4)$
