No.157 Intercepts of a Line

POINT

On the x-axis, \(y=0\). On the y-axis, \(x=0\). Use these facts to calculate the intercepts.

Example

The line is \(y=\frac23x+4\). Find its intersections with the x-axis and y-axis.

Find both intercepts.

x-axis: \((-6,0)\)
y-axis: \((0,4)\)

TRY 1

For \(y=-2x+6\), find both intercepts.

x-axis \((3,0)\); y-axis \((0,6)\).

TRY 2

For \(y=\frac12x-3\), find both intercepts.

x-axis \((6,0)\); y-axis \((0,-3)\).
