Answer: 
.
Step-by-step explanation:
As we know ,
The slope of a line that passes through 
and 
is given by :
The slope of a line that passes through (1 , 7K), and (-3,5K) =
Hence, the slope of the given line is .
Answer:
x= 5/4 ; y= -7/4
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
3x+y=2;5x−y=8
Step: Solve3x+y=2for y:
3x+y+−3x=2+−3x(Add -3x to both sides)
y=−3x+2
Step: Substitute−3x+2foryin5x−y=8:
5x−y=8
5x−(−3x+2)=8
8x−2=8(Simplify both sides of the equation)
8x−2+2=8+2(Add 2 to both sides)
8x=10
8x
8
=
10
8
(Divide both sides by 8)
x=
5
4
Step: Substitute
5
4
forxiny=−3x+2:
y=−3x+2
y=−3(
5
4
)+2
y=
−7
4
(Simplify both sides of the equation)
Answer:
x=

Answer:
fr it does that to me lol and then i have to press on the ad fr
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
Let's call the number x.
Subtract 3 from both sides:
Multiply both sides by 2:
