What is the slope of a line that is perpendicular to the line represented by x=3?
give the coordinates of a point on the line whose equation in point-slope form is )=1/2(x-5)

Step-by-step explanation:

1. The equation x=3 describes a vertical line. A perpendicular line will be horizontal. It will have no "rise" for any length of "run." The slope is zero.

__

2. The point-slope form of the equation for a line with slope m through point (h, k) is ...

  y -k = m(x -h)

You can read the values of h and k from your equation. They are ...

So, a point on the line is (h, k) = (5, -2).

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
