For the graph x = -3 find the slope of a line that is perpendicular to it. a.) -3 b.) -1/3 c.) 0 d.) undefined

When given a line x = "some number", this is a vertical line. No matter what the y value is the x is always -3. A vertical line has undefined slope (or no slope). The line that's perpendicular is a horizontal line. A horizontal line has zero slope - -the x changes, the y does not.

Thus, a line a perpendicular to x = -3 has zero slope. (choice "C")

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
