Answer:
slope = 4
The line is increasing
Step-by-step explanation:
slope can be found through the equation [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. So, if we plug these points in, we get [tex]\frac{7-3}{8-7}[/tex], which simplifies to 4. So, the slope is 4.
Since the slope is positive, the line is increasing.
