What is the slope of the line that passes through (2, 12) and (4, 20) ?
2 answers:
Answer: 4
Step-by-step explanation:
The slope of a line passing through two points (a,b) and (c,d) is given by :-
The given points : (2, 12) and (4, 20)
Then , the slope of a line passing through two points (2, 12) and (4, 20) is given by :-
Hence, the slope of the line through the points (2, 12) and (4, 20) = 4

Answer:
The point of intersection of the lines is .
Thus, Ariyonne's claim is incorrect.
Step-by-step explanation:
Given equations:
1)
2)
To find the point of intersection, we need to solve the given system of equations.
In order to solve the system we will use substitution method.
We will substitute value of from first equation in the second equation and solve for
So, we have
Multiplying both sides by 2 to remove fraction.
Using distribution.
Subtracting both sides by
Adding 4 to both sides.
Dividing both sides by 7.
We can find value of by plugging in
in the first equation.
So, the point of intersection of the lines is .
Thus, Ariyonne's claim is incorrect.
