The slope of CD is

The slope of the perpendicular bisector is the negative reciprocal,

The perpendicular bisector passes through M, the midpoint of CD
M =( (0+2)/2, (-4 + 6)/2) = (1, -1)
So point slope form for the perpendicular bisector is

Solving for y gives slope intercept form.

Answer: y=(-1/5)x-4/5
Answer:
y = 0.1x - 4
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (-3, 7)
Points on the y-axis (y1, y2) = (-7, -6)
First of all, we would find the slope;
Mathematically, slope is given by the formula;
Substituting into the equation, we have;
Slope = (-6 - (-7))/(7 - (-3))
Slope = (-6 + 7)/(7 + 3)
Slope = 1/10
Slope = 0.1
Next, we would write the equation using the formula;
y - y1 = m(x - x1)
y - (-7) = 0.1(x - (-3))
y + 7 = 0.1(x + 3)
y + 7 = 0.1x + 3
y = 0.1x + 3 - 7
y = 0.1x - 4
Answer:
5/6
Step-by-step explanation:
4,5,6- Numbers greater than 3

The variable in this algebraic expression is b
Answer:
19 Cars
Step-by-step explanation:
Write a linear equation:
y=7x+53
Y = Total money
X = cars parked
If we want to earn 186 dollars a day then sub y for 186 and solve x:
186=7x+53
186-53=7x
133=7x
7x=133
x=133/7
x=19
This means that he will need to park 19 cars a day to earn a total of 186 dollars in one day.
