I'm thinking n would be -2 but when I add it stops at 11 and when I put -3 in its place it says 14 so I'm guessing maybe -2.4

Is line p || to line q? Why?
bonufazy [111]

Step-by-step explanation:

yes, because the angles match. per rule of intersecting lines the angles in one side of an intersected line are the same but mirrored on the other side of the line.

since q behave exactly as p would regarding the intersecting angles, they are parallel.

What is the slope of the line between the points (2,-1) and (5,-3)
Ilya [14]

Answer:

The slope of the line between the points (2,-1) and (5,-3) is m=-\frac{2}{3}

Therefore m=-\frac{2}{3}

Step-by-step explanation:

Given that the line between the points (2,-1) and (5,-3)

To find the slope of the line between the points (2,-1) and (5,-3) :

The formula for slope is m=\frac{y_2-y_1}{x_2-x_1}

Let (x_1,y_1) , (x_2,y_2) be the given points (2,-1) and (5,-3) respectively

Now substitute the values of the points in the formula

m=\frac{-3-(-1)}{5-2}

=\frac{-3+1}{3}

=\frac{-2}{3}

Therefore m=-\frac{2}{3}

The slope of the line between the points (2,-1) and (5,-3) is m=-\frac{2}{3}

Could some one help pls ill mark brainlist
Effectus [21]

Add alike terms. Basically you add stuff together with the same variable! Since -8y and +3y have a y variable, they can be added together. Same with x.

-8y + 3y = -5y. This is because you’re adding 3 from a negative number.

5x - 9x = -4x. You’re subtracting 9 from a positive number.

That is as simple as it can get, so you put those two numbers in the same equation.

The simplest expression is:

-5y - 4x
