A) What is the y-intercept of y = 3x ?
(b) What is the slope of y = -x - 2 ?

0 and - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

(a)

y = 3x or y = 3x + 0 has c = 0 ← y- intercept

Thus line passes through the origin

(b)

y = - x - 2 has m = - 1 ← slope

it's

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
