Interactive practice questions

Consider the following graph.

Loading Graph...

A Cartesian plane has both its $x$x- and $y$y-axes ranging from $-7$−7 to $7$7. Both axes are marked with intervals of $1$1 unit. A diagonal line is plotted on the Cartesian plane. The line moves downward from left to right. The line passes through the $x$x-axis at $\left(3,0\right)$(3,0). The line passes through the $y$y-axis at $\left(0,4\right)$(0,4). The points are not marked and their coordinates are not explicitly labeled or given. The line continues to move downward and extends beyond the visible part of the graph.

a

State the value of the $x$x-intercept.

b
