Although gentrification can revitalize cities by rehabilitating
vova2212 [387]

Answer: Higher rents causing displacement of existing residents.

Explanation:

Gentrification is the process of remodeling a neighborhood, street or building to increase its value and attract a population of a higher social status.

This process is highly controversial since the current inhabitants of the area usually cannot bear the costs of continuing to live in the same neighborhood and must move. Residents are sometimes forcibly evicted before remodeling.

Let m and c represent constants with m nonzero. What is the equation of the line perpendicular to y=m(x+c) and with the same y-i
nikklg [1K]

Answer:

y = -\frac{1}{m}x + mc

Explanation:

Given

y = m(x + c)

Required

Determine an equation of a perpendicular line but with the same y intercept

y = m(x + c)

Open bracket

y = mx + mc

A linear equation is represented with:

y = ax + b

Where

a = slope

b = y\ intercept

By comparison:

a = m

b = mc

So, the slope of y = m(x + c) is m

Because the new line is perpendicular to y = m(x + c), the relationship between their slopes is:

a_2 = -\frac{1}{a_1}

Where

a_1 = slope of the first equation

a_2 = slope of the second equation

Substitute m for a_1 in a_2 = -\frac{1}{a_1}

a_2 = -\frac{1}{m}

Hence, the slope of the new equation is: -\frac{1}{m}

From the question, we understand that they have the same y intercept.

So, the equation of the new equation is:

y = -\frac{1}{m}x + mc
