Answer:
3y = -2x + 1
Step-by-step explanation:
Equation of given line is 2y = 3x + 2
==> y = (2/2)x + 1
Slope = 3/2
Slope of perpendicular line is negative of reciprocal of given line ie slope = -2/3
So equation of perpendicular line is of the form
y = (-2/3)x + c where c is a constant
Given that this passes thru x= -1, y =1 we can substitute these values in the above to get
1 = (-2/3)(-1) + c
This yields 1 = (2/3) + c or c = 1-2/3 = 1/3
So the equation of the perpendicular line is
y = (-2/3)x + 1/3
3y = -2x + 1
So if say the width is "w", double that is 2*w, or 2w 1 unit less than that is 2w - 1, check the picture below
since it cannot be a negative value, so... is not -3
what are the dimensions? well, length = 2w - 1, and w = well is above :)

Answer:
16. y=-5x-20; 17. y=6x+18, or factored y=6(x+3)
Step-by-step explanation:
Your slope is -5
y=-5x+b, solve for b by pluging the point (-3,-5) in for x and y
-5=-5(-3)+b, solve for b
-20=b, now rewrite the equation
y=-5x-20
Your slope is 6
y=-5x+b, solve for b by pluging the point (-3,-0) in for x and y
0=6(-3)+b, solve for b
18=b, now rewrite the equation
y=6x+18, or factored y=6(x+3)
Answer:
C. 14 is your answer.
Step-by-step explanation:
Basically what you do is you take the 20, -4, and -2 and add them together.
C. 14 is your answer.
