Graph the line using a point and a slope. Write the equation of each line. c
a line that contains point (0, −3) and perpendicular to another line whose slope is 2.

Graph attached.

Step-by-step explanation:

The product of slope of line (i) and slope of line (ii) should be equal to -1 (product of slopes of two perpendicular lines = -1)

i.e

Slope of line (i) × 2 = -1

Slope of line (i) =

To find the equation of line (i), we need another point (x,y) on the line.

Slope (m) = change in y ÷ change in x =

y = - 3
