Answer:
y = ix + 6i + 4
Step-by-step explanation:
Since the line has undefined slope or indefinite slope we connote that the slope is (i)
Slope(m) of straight line = change in y ÷ change in x
Taking another point (x,y) on the line:
i = [tex]\frac{y - 4}{x - -6}[/tex]
i = [tex]\frac{y - 4}{x + 6}[/tex]
Cross multiplying gives;
y - 4 = ix + 6i
y = ix + 6i + 4
