that i would have to go with the 1st or 3rd lne
Answer:
Divide 108 by 12 since there are 12 inches in a foot.
108 ÷ 12 = 9
Points (1, 7) and (-3, 2)
Slope for a line between (x₁, y₁) and (x₂, y₂) , m = (y₂ -y₁) / (x₂- x₁)
The slope for the line joining the two points = (2 - 7) / (-3 - 1) = -5/-4
Slope = 5/4
Hence the perpendicular bisector would have a slope of -1/(5/4) = -4/5
By condition of perpendicularity
For points (1, 7) and (-3, 2),
Formula for midpoints for (x₁, y₁) and (x₂, y₂) is ((x₁ +x₂)/2 , (y₁+ y₂)/2)
Midpoint for (1, 7) and (-3, 2) = ((1+ -3)/2 , (7+2)/2) = (-2/2, 9/2)
= (-1, 9/2)
Since the slope of perpendicular bisector is -4/5 and passes through the midpoint (-1, 9/2)
Equation y - y₁ = m (x - x₁)
y - 9/2 = (-4/5) (x - -1)
y - 9/2 = (-4/5)(x + 1)
5(y - 9/2) = -4(x + 1)
5y - 45/2 = -4x - 4
5y = -4x - 4 + 45/2
5y + 4x = 45/2 - 4
5y + 4x = 22 1/2 - 4 = 18 1/2
5y + 4x = 37/2
10y + 8x = 37
The equation of the line to perpendicular bisector is 10y + 8x = 37
Answer:
-7x+6
Step-by-step explanation:
Use the distributive property.
Add the negative in front of each number in the parenthesis.
- (7x) -(-6)
Since 6 is negative, a negative multiplied by a negative is equal to a positive. Change the negative in front of the 6 into a positive.
-7x + 6
(1,0),(6,-3)
slope(m) = (-3 - 0) / (6 - 1) = -3/5
y - y1 = m(x - x1)
slope(m) = -3/5
(6,-3)....x1 = 6 and y1 = -3
now sub....and pay attention to ur signs
y - (-3) = -3/5(x - 6)......this is not the final answer....but it seems to be what ur question is asking for.
