(-4,2) ;m=-1/3 You have to use this formula y=mx+b
1 answer:
Answer:
y = -1/3x +2/3
Step-by-step explanation:
We assume you want the equation of the line through the given point. The point-slope form of the equation is a good place to start.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -2 = -1/3(x +4) . . . . . . fill in given values
y = -1/3x -4/3 +2 . . . . . eliminate parentheses, add 2
y = -1/3x +2/3 . . . . . . . simplify

Given:
The system of equations is:
Line A:
Line B:
To find:
The solution of given system of equations.
Solution:
We have,
...(i)
...(ii)
Equating (i) and (ii), we get
Divide both sides by 2.
Substituting in (i), we get
The solution of system of equations is (-4,-8).
Now verify the solution by substituting in the given equations.
This statement is true.
Similarly,
This statement is also true.
Therefore, (-4,-8) is a solution of the given system of equations, because the point satisfies both equations. Hence, the correct option is C.
