Answer:
Slope of line (i) = 1.5
Step-by-step explanation:
- Line (i) is perpendicular to;
- Line (ii) whose equation is y = [tex]-\frac{2}{3} x + 12[/tex]
The slope of line (ii) = [tex]-\frac{2}{3}[/tex]
* Mathematics rule: The product of slopes of two perpendicular lines = -1
∴ The slope of line (i) = -1 ÷ [tex]-\frac{2}{3}[/tex] = 3/2 = 1.5
