Answer:

For every object in space, it is moving a speed. Planets, asteroids, comets, even stars move across space very quickly. Comets are nothing more than just rock, dirt, and ice. When it moves, the tail is formed due to its movement. It can even be created by water vapor when it goes around a star because it has ice on it.

On a coordinate plane, a line goes through (negative 3, negative 3) and (negative 1, 5). What is the equation of the line parall

DENIUS [597]

Answer:

y=4x-16

Explanation:

The general form of the equation of a line is: y=mx+x, where m is the gradient and c is the y-intercept.

Given points (-3,-3) and (-1,5)

We are to find the equation of the line parallel to the given line with an x-intercept of 4.

First, we determine the value of the gradient of the line.

Gradient,

$m=\frac{y_2-y_1}{x_2-x_1} \\=\frac{5-(-3)}{-1-(-3)} \\=\frac{5+3}{-1+3}\\=\frac{8}{2}\\m=4$

Two lines are parallel if their gradients $m_1 \: and \: m_2$ are equal.

The gradient of the line parallel to the given line $m_2=4$

Since the x-intercept of the new line is 4, a point on the new line, $(x_1,y_1)=(4,0)$

Substituting $(x_1,y_1)=(4,0)$ into the equation of a line: , $y-y_1=m(x-x_1),$ we have:

$y-0=4(x-4)\\$Therefore:\\y=4x-16$

Therefore, the equation of the line is: y=4x-16
