Y-y1=m(x-x1)
is the equation of a line that passes through the pionts (x1,y1) and has a slope of m

find slope

slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
2 points are (-4,2) and (4,-1)
slope=(-4-2)/(4-(-4))=-6/(4+4)=-6/8=-3/8

the eqaution is either
y-2=-3/8(x+4) or
y+1=-3/8(x-4)


B is answer

Youyou havehave aa seriousserious doubledouble pastepaste problemproblem

the equation of the line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given

the point is (5,-3) and the slope is 23 (or it could be 2/3)
x1=5
y1=-3
y-(-3)=23(x-5)
y+3=23(x-5) is answer

Determine if the sides form a right triangle.
Law Incorporation [45]

Answer:

Yes, it's a right-angle triangle

Step-by-step explanation:

3 root 2 is 4.24

3 root 3 is 5.2

3 root 5 is 6.71

3 root 5 is the longest side, so must be the hypotenuse.

a^2 + b^2 = c^2

(3 root 3)^2 + (3 root 2)^2 = c^2

45 = c^2

Square root both sides

C = root 45

( simplified to C= 3 root 5)

Thus, it is a right-angle triangle.

(Root means a square root)

Hope this helps!

tankabanditka [31]
<h3>Answer: Choice A) 3.5</h3>

Work Shown:

The point (8,28) is the furthest to the right on the graph. We have x = 8 and y = 28 pair up here. Divide the y over the x

y/x = 28/8 = 3.5

side note: the tickmarks on the y axis go up by 4 each time
