What is slope of the line parallel to the line containing points (2,5) and (6,-11)
Ksivusya [100]

The parallel lines have the same slope.

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (2, 5) and (6, -11).

Substitute:

m=\dfrac{-11-5}{6-2}=\dfrac{-16}{4}=-4

What value of X makes this equation true -90 equals -100+ X
raketka [301]

-90 = -100 + x

To solve for X, you need to isolate it ( get it by itself).

Add 100 to each side:

-90 + 100 = -100 + x + 100

Simplify:

10 = x

X = 10
