Question

Find the slope of the line passing through the pair of points. (–4, 5) and (0, 2)

Answer 1

yep

Answer 2

slope is determined by y2-y1/x2-x1

(5-2)/(-4-0)=3/-4 or -3/4

Answer 3

Find the slope of the line passing through the pair of points.
(–2, –3) and (–2, –7)

Answer 4

thank u i get it now

Answer 5

I don't think so dalia_lam....a fraction of -4/0 has an undefined slope; it is a vertical line

Answer 6

The answer isn't 0...do you see that?

Answer 7

@DSS sorry, you're right. If the denominator is 0 the the slope is undefined.

Answer 8

Is the equation a direct variation? If it is, find the constant of variation.
y = 2x

Answer 9

????????

Answer 10

yes y=kx k is the constant
so y=2x 2 is the constant

Answer 11

Is the equation a direct variation? If it is, find the constant of variation.
y = x – 2

Answer 12

Direct Variation: The statement " y varies directly as x ," means that when x increases, y increases by the same factor. In other words, y & x always have the same ratio:

y/x= k where k is the constant of variation.

We can also express the relationship between x and y as:
y = kx where k is the constant of variation.

y=x-2 is not a direct variation

Answer 14

y=x-2 is not a direct variation. It is a linear equation where the constant is -2

Answer 15

Is the equation a direct variation? If it is, find the constant of variation.
