let x = {p ∈ z | p = 5a + 2 for some integer a}, y = {m ∈ z | m = 4b + 3 for some integer
b}, and z = {n ∈ z | n = 4c − 1 for some integer c}.
is x ⊆ y ? (2pts)
justify your answers carefully. (in other words, provide a proof if the statement is true or a disproof if the statement is false.) (8 pts)

answer: t=3

step-by-step explanation:

answer:   c ?

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
