Answer:
Slope = [tex]-\frac{5}{6}[/tex]
Step-by-step explanation:
Step 1: Find the slope
Slope = [tex]\frac{y2-y1}{x2-x1}[/tex]
Slope = [tex]\frac{18 - 3}{-21 - (-3)}[/tex]
Slope = [tex]\frac{15}{-21 + 3}[/tex]
Slope = [tex]\frac{15}{-18}[/tex]
Slope = [tex]-\frac{5}{6}[/tex]
Answer: Slope = [tex]-\frac{5}{6}[/tex]
