Answer:
y = 1/2x + 4
Step-by-step explanation:
Use the formula for the equation of a line.
y = mx + b
Where m is the slope, and b is the y-intercept.
The slope is given.
y = 1/2x + b
The points (x, y) are given.
(4, 6)
Put y as 6 and x as 4, solve for b.
6 = 1/2(4) + b
6 = 2 + b
6 - 2 = b
4 = b
The y-intercept is 4 or (0, 4).
The equation of the line is y = 1/2x + 4.
Answer:
k=3
Step-by-step explanation:
The given system of equations are
We need to find the value of k if the given system of equation have infinite number of solutions.
If two equations and
have infinite number of solutions, then
Using this we get
Therefore, the value of k is 3.
