Write an equation in standard form for the line that has undefined slope and passes through (-6, 4)
Nikitich [7]

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 = \frac{y - 4}{x - -6}

i = \frac{y - 4}{x + 6}

Cross multiplying gives;

y - 4 = ix + 6i

y = ix + 6i + 4
