We use the properties of equality to rewrite equations and solve equations for a variable. These properties allow us to maintain

a balance between the two sides of the equation.
Why is it important to keep the two sides of an equation balanced when solving? What other properties do we use to rewrite expressions and equations?

Step-by-step explanation:

An important property of equations is one that states that you can add the same quantity to both sides of an equation and still maintain an equivalent equation. ... If you think of an equation as being like a balance scale, the quantities on each side of the equation are equal, or balanced.

Find the midpoint of PQ¯¯¯¯¯¯¯¯ with endpoints P(−7, 0) and Q(1, 8). Then write an equation of the line that passes through the
Lilit [14]

Answer with Step-by-step explanation:

We are given that

P(-7,0) and Q(1,8)

We have to find the midpoint of PQ and write an equation of the line that passes through the midpoint.

Mid-point formula: x=\frac{x_1+x_2}{2}, y=\frac{y_1+y_2}{2}

By using this formula ,

The mid point of PQ

x=\frac{-7+1}{2}=-3, y=\frac{0+8}{2}=4

Hence, the midpoint of PQ is (-3,4).

Slope of PQ=m=\frac{y_2-y_1}{x_2-x_1}=\frac{8-0}{1+7}=1

Slope of perpendicular line=\frac{-1}{slope\;of PQ}=-1

The equation of line which is passing through the point (-3,4) with slope -1 is given by

y-y_1=m(x-x_1)

The equation of line which is passing through the point (-3,4) with slope -1 is given by

y-4=-1(x+3)

y-4=-x-3

y=-x-3+4

y=-x+1
