Find the slope of a line that passes through the
Doss [256]

Given that,

Point 1 = (-6,9)

Point 2 = (2,9)

To find,

The slope of a line that passes through the given pair.

Solution,

We have,

x₁ = -6, x₂ = 2, y₁ = 9, y₂ = 9.

The formula for the slope of a line is given by :

m=\dfrac{y_2-y_1}{x_2-x_1}\\\\=\dfrac{9-9}{2-(-6)}\\\\=0

Hence, the slope of the line that passes through the given pair is 0.

What is the equation in point slope form of the line that passes through the point (−1, −3) and has a slope of 4?
blondinia [14]

Answer: y + 3 = 4 (x +1 )

Step-by-step explanation:

The eqution of a line in point- slope form is given as :

y-y_{1} = m(x-x_{1} )

Where m is the slope and (x_{1} , y_{1}) is the given point

substituting the values into the formula , we have:

y - (-3) = 4 ( x - {-1) )

y + 3 = 4 ( x + 1)

This is the equation of the line in point-slope form.
