What is an equation of a line perpendicular toy=-\frac{1}{2}x-5and passing through (6, -4) ? (You'll have to distribute from point-slope)

x/3-10=8

x/3=18

x=48

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,
