Put them together it’s a mixed fraction
Answer:
The equation of your line is y=1x+2
Step-by-step explanation:
first you take y2-y1/x2-x1
y2=-1 y1=5
x2= -3 x1= 3
that gives you your slope so (-1-5)/ (-3-3) = 1
y=mx+b
mx is your slope
y=1x+b
to solve for b you input your slope and one of your points (I used (3,5)
5=1(3) +b
solve for b and you get 2
then put your mx and b into the equation of a line
y=1x+2
and thats your answer
You can also check your work by using a graphing calculator and checking that the line goes through those two points.

<u>way 1</u>:
rule: for an equation where no roots P+Q=0. It means, Px-Qx=0, ⇔ x(P-Q)=0, ⇔ P=Q.
for answer 'D' P=Q=15.
<u>way 2</u>:
rule: if an equation of the line has a form y=kx+b, then y₁||y₂ if k₁=k₂. It means, for y₁=Px-45 || y₂=Qx+75, then P=Q. P=Q, if 'D' answer.
Answer: D
Answer:
the answer is X=-8 or X= 2
Step-by-step explanation:
subtract 10 from both sides in order to eliminate 10.
x^2 + 6x -16
find two factors of -16 that sum up to 6.
-2 and 8 are two factors of -16 that sum up to 6.
(x-2)(x+8)
x-2= 0, x= 2
x+8= 0, x = -8
