What is a point-slope equation of the line with slope -10 that goes through the point (1,4)? a) y-4=-10(x-1)
b) y-4=10(x-1)
c) y+4=10(x+1)
d) y+4=-10(x+1)

The answer is option A

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

where

m is the slope

( x1 , y1) is the point

From the question

the slope is - 10

the point is (1,4)

So the equation of the line is

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
