Answer:
The answer to your question is: y = -2/3 x + 18
Step-by-step explanation:
Data
Point = (-9, 12)
line y = 3/2x -1/2 perpendicular
Process
The line must be perpendicular to the line given. Then,
slope is the line given = 3/2, we change it because the lines must be perpendicular ,
New slope M = -2/3
New line y-y1 = m(x - x1)
y - 12 = -2/3 (x + 9) Substitution
3( y - 12) = -2(x + 9)
3y - 36 = -2x - 18 Simplify
3y = -2x - 18 + 36
3y = -2x + 18
y = -2/3 x+ 18 Result
Just graph the coordinates
this picture is the different quadrants on the graph, whichever quadrant the coordinate is in, is what you put in the 2nd column
for example: (-2,-3) is in the 3rd quadrant
if its not in a quadrant its either on x or y axis, so its just on the line, and i assume you know which axis is which
for number 4. You just do subtraction, and then if its negative, it becomes positive since its asking for the absolute value
for example: |-24-11| > |-35| > 35
