Determine the equation of the line that passes through the points (-1 , 10) and (2,4)
docker41 [41]

Given:

The two points are (-1,10) and (2,4).

To find:

The equation of line which passes though the given points.

Solution:

If a line passes through two points, then the equation of line is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

The line passes through (-1,10) and (2,4). So, the equation of line is

y-10=\dfrac{4-10}{2-(-1)}(x-(-1))

y-10=\dfrac{-6}{2+1}(x+1)

y-10=\dfrac{-6}{3}(x+1)

y-10=-2(x+1)

Using distributive property, we get

y-10=-2x-2

Adding 10 both sides, we get

y=-2x-2+10

y=-2x+8

Therefore, the required equation of line is y=-2x+8.

Which equation represents the explicit formula for a constant velocity arithmetic sequence?
k0ka [10]

The equation which represents the explicit formula for a constant velocity arithmetic sequence is; Choice A; xₙ = x₁+(n-1)(v•△t).

<h3>Which equation among the answer choices represents the explicit formula for a constant velocity arithmetic sequence?</h3>

It follows from convention that an arithmetic sequence is usually defined by an expression of the form;

T(n) = T(1) + (n-1)×d in which case, d = common difference.

Consequently, in the event that the velocity in discuss is constant, it follows that the required expression is; Choice A; xₙ = x₁+(n-1)(v•△t).

Therefore, xₙ = x₁+(n-1)(v•△t) represent the equation for explicit formula for a constant velocity arithmetic sequence.
