Chapter 5 - Linear Functions - 5-4 Point-Slope Form - Lesson Check: 5

Answer

We can identify a point on the graph of the line, $(x_1,y_1)$, and its slope, $m$.

Work Step by Step

The point-slope form of an equation of a non-vertical line with slope $m$ and through point $(x_1,y_1)$ is $y-y_1=m(x-x_1)$. The equation includes both the point $(x_1,y_1)$ and the slope $m$, so they can be identified through the equation.
