Factorise:<br> 3x3-3x2y+xy2-x2y

qaws [65]

$3x^3-3x^2y+xy^2-x^2y$

All terms have an x in them, so you factor that out first to get

$x(3x^2 -4xy+y^2)$

Now the 2nd degree equation will be of the form (3x- ... y)(x- ... y) and by just trying you find that the ... is just 1. So the factorization is:

$x(3x - y)(x - y)$

What is the slope of the line that passes through the points (-2,5) and (3,-4) in the standard (x,y) coordinate plane

Scorpion4ik [409]

To find the slope between two coordinates, you use the formula:

m = y2 - y1/x2 - x1

If coordinate A is (-2, 5) and coordinate B is (3, -4), then:

y2 = -4

y1 = 5

x2 = 3

x1 = -2

So, just substitute the points into the formula.

m = -4 - 5/3 - (-2)

m = -9/5

The slope of the line is -9/5.

<h3><u><em>Answer:</em></u></h3>

The slope of the line through ( -2 , -5 ) and ( -6 , 7 ) is <u>-3</u>

<h3><u><em>Solution:</em></u></h3>

Correct option is

Slope of the line $=\frac{y_2-y_1}{x_2-x_1}$

Here $x_1=-2,y_1=-5$ and $x_2=-6,y_2=7$

∴ $m=\frac{7-(-5)}{(-6)-(-2)}=\frac{12}{-4}=-3$

Therefore, the slope of the line through ( -2 , -5 ) and ( -6 , 7 ) is <u>-3</u>
