Answer:
perpendicular
Step-by-step explanation:
If 2 lines are parallel then their slopes are equal
If 2 lines are perpendicular then the product of their slopes = - 1
Here
- ×
= - 1
Then the 2 lines are perpendicular

Step-by-step explanation:
Intercepts:
The line which intersect on x-axis and y-axis are called intercepts.
There are two intercepts:
x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.
y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.
Given:
We have General Equation for POINT-SLOPE form for a line is given as
where,
m = Slope of Line
c = y-intercept
On Comparing the given Equation with Point-Slope form we have
Therefore,
Answer:
Swimming speed in still water is approximately 1.5 mph
Step-by-step explanation:
Given the speed of the current = 1 mph
distance she swims upstream =2 miles,
the total time = 5 hours.
She swam 2 miles upstream against the current and 2 miles back to the dock with the current. The formula that relates distance, time, and rate is
Let x be the speed in still water.
Then her speed with the current is x + 1, and
her speed against the current is x – 1.
Total time is equal to 2 miles with upstream and 2 miles downstream.
Now Using quadratic formula to solve above equation we get;
Since speed must be positive, Hence speed of still water is about 1.5 miles per hour.
