Answer:
yes
Step-by-step explanation:
put a dot on the x line.
The slope of a line is given by the change in y coordinates over the change in x coordinate.
The slope of line DE will be (4 - -3)/ (7-1) = 7/6
If M1 and M2 are slopes of two perpendicular lines at a point then
M1× M2 = -1
Thus, the slope of a perpendicular to line DE will be -6/7.

The answer is D
Explanation)
Multiplication identity property is when a factor is multiplied by 1
Answer:
Step-by-step explanation:
The equation of a line:
We have
substitute:
The formula of a distance between a point and a line:
General form of a line:
Point:
Distance:
Convert the equation:
|<em>subtract 
from both sides</em>
|<em>multiply both sides by 3</em>
Coordinates of the point:
substitute:
|<em>multiply both sides by 
</em>
|<em>divide both sides by 3</em>
Finally:
