Answer:
1. The slope of the line is .
2. The value of a is 18.
Step-by-step explanation:
If a line passes through two points, then the slope of the line is
(1)
It is given that the line passes through the points (-a + 3, b - 3) and (a + 3, -b). So, the slope of the line is
The slope of the line is .
(2)
If the line passing through the points (a, 1) and (6, 5), then the slope of the line is
If the line passing through the points (2, 7) and (a + 2, 1), then the slope of the line is
The slopes of two parallel lines are same.
On cross multiplication we get
Divide both sides by -2.
Therefore the value of a is 18.
Answer:
or
Step-by-step explanation:
We know that the slope of the line is 1, so we can write it in terms of any two points belonging to the line, as per the difinition of slope:
We can use instead of any general point (x,y) on the line, and for
the point we are interested in: (11,4)
That way the slope can be written as:
Next we can solve for y if this format is the one your instructor prefers:
