Answer:
Step-by-step explanation:
Slope of two lines that are perpendicular to each other is 1.
If one line is , then its slope = 3 [by comparing to the linear equation y= mx+c, here m=3]
Let n be the slope of the required line, then
Equation of line with slope n and passers through (a,b) is
Equation of line with slope n= and passes through point ( 0,-4) :
Hence, Required equation :
Draw a square with side length of 4. All four angles are 90 degrees and all four sides are 4.
Then draw a rectangle with length of 9 and with of 2. All four angles would be 90 degrees, but the proportion of the 2 sides are different when compared to the sides of the square.
