# Appendix B - Coordinate Geometry and Lines - B Exercises: 23

#### Answer

$y = \frac{2}{3}x + \frac{19}{3}$

#### Work Step by Step

We are told to find the equation of the line that satisfies the following conditions: Passes through the point $(1,7)$, and has a slope of $\frac23$, To find the equation of the line we use point slope form: $y−y_1=m(x−x_1)$ $x_1=1$ $y_1=7$ $m=\frac23$ $y−7=\frac23(x−1)$ $y=\frac23x−\frac23+7$ $y = \frac{2}{3}x + \frac{19}{3}$
