Y-8= - * - 4 y=-* 4 (3,-5) no solution an infinite number of solutions

muminat

Given:

The system of equation is

$y-8=-\dfrac{1}{3}x-4$

$y=-\dfrac{1}{3}x-4$

To find:

The solution of given system of equations.

Solution:

The slope intercept form of a line is

$y=mx+b$

Where, m is slope and b is y-intercept.

Write the given equation in slope intercept form.

The first equation is

$y-8=-\dfrac{1}{3}x-4$

$y=-\dfrac{1}{3}x-4+8$

$y=-\dfrac{1}{3}x+4$ ...(i)

Here, slope is $-\dfrac{1}{3}$ and y-intercept is 4.

The second equation is

$y=-\dfrac{1}{3}x-4$ ...(i)

Here, slope is $-\dfrac{1}{3}$ and y-intercept is -4.

Since the slopes of both lines are same but the y-intercepts are different, therefore the given equations represent parallel lines.

Parallel lines never intersect each other. So, the given system of equation has no solution.

Hence, the correct option is B.

Point A (-2-10) is reflected over the x axis write the coordinates of A

Arada [10]

The answer is (-2, 10) because when reflecting over the x, change the sign of y. When reflecting over the y, change the sign of x.

What is the distance between point A and point B to the nearest tenth?

drek231 [11]

The answer is C. If you use the pythagorean theorem, $a^2+b^2=c^2$ , and connect the two points together at a right angle and pug in the lengths of the two lines to the equation then the answer should be C.
