Graph the line using a point and a slope. Write the equation of each line.
1 answer:
Answer:
Graph attached.
Step-by-step explanation:
- Line (i) contains point (0, -3)
- It's perpendicular to line (ii) whose slope is 2
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) =
<u>To find the equation of line (i), we need another point (x,y) on the line.</u>
<u />
Slope (m) = change in y ÷ change in x =
y = - 3
