Answer:
y-4=-7(x-1) OR y-(-10)=-7(x-3)
Step-by-step explanation: The point-slope form is -
=
(
-
)
In slope-intercept form, the equation would be y = -7x + 11
You could find the slope by using the slope equation, .
Using that, you would get -7. Thus by inserting one of the points and the slope in the point-slope equation, you will get your answer.
The Pythagorean theorem works.
Therefore the perimeter is 12 + 9 + 15 = 36 in. (B)
Therefore the perimeter is 12 + 9 + 15 = 36 in. (B)
