What is the slope between the points (5,-4) and (-3,4) -1 4 0 1

kumpel [21]

Answer:

The answer is -1.

Step-by-step explanation:

You have to apply gradient formula :

$m = \frac{y2 - y1}{x2 - x1}$

So you will have to substitute the coordinates into the equation. Let (x1,y1) be (-3,4) and (x2,y2) be (5,-4) :

$m = \frac{ - 4 - 4}{5 - ( - 3)}$

$m = \frac{ - 8}{8}$

$m = - 1$

Which illustrates the construction of a perpendicular to a line from a point on the line?

quester [9]

I believe the correct answer from the choices listed above is the last option. The last option clearly describes the illustration of the construction of a perpendicular to a line from a point on the line where you start on a point in the line. Using an arbitrary radius, draw arcs intersecting the line at two points. 
Hope this answers the question. Have a nice day.
