How do i do this question?

y = 1/4x + 5

slope = 1/4

perpendicular slope = -4

coordinates (0, 2)

y - y1 = m(x - x1)

y - 2 = -4(x - 0)

y = -4x + 2

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
