Hello!
Find the slope using the slope formula:
m = (y2 - y1) / (x2 - x1)
Plug in the points (-2, 8) and (0, 6) to solve:
m = (6 - 8) / (0 - (-2))
m = -2 / 2
m = -1
The y-intercept of the function is the y-value when x = 0.
According to the table, at x = 0, y = 6. Therefore, the y-intercept is (0, 6).
The correct answer is B.

Given:
The equation of a line is
Line v passes through point (6,6) and it is perpendicular to the given line.
Line w passes through point (-6,10) and it is parallel to the line v.
To find:
The equation in slope intercept form of line w.
Solution:
Slope intercept form of a line is
...(i)
where, m is slope and b is y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get
So, slope of given line is .
Product of slopes of two perpendicular lines is -1.
Line w is perpendicular to the given line. So, the slope of line w is .
Slopes of parallel line are equal.
Line v is parallel to line w. So, slope of line v is also .
Slope of line v is and it passes thorugh (-6,10). So, the equation of line v is
where, m is slope.
Adding 10 on both sides, we get
Therefore the equation of line v is .
