Which is an equation in point-slope form for the line that passes through the points (−1,4) and (3,−4) ?

y+4=−2(x−3)
y−4=2(x+3)
y+4=2(x−3)
y−3=−2(x+4)

We know that Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

Given Points are (-1 , 4) and (3 , -4)

here x₁ = -1 and x₂ = 3 and y₁ = 4 and y₂ = -4

⇒

We know that the form of line passing through point (x₀ , y₀) and having slope m is :

y - y₀ = m(x - x₀)

Here the line passes through the point (3 , -4)

x₀ = 3 and y₀ = -4 and we found m = -2

Equation in Point slope form : y + 4 = -2(x - 3)

First Option is the Answer

its 69.420

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
