Answer:
The slope is undefined and the equation of the line is x = 9 ⇒ C
Step-by-step explanation:
- Parallel lines have the same slopes and different y-intercepts
- The slope of any vertical line is undefined
- The equation of any vertical line is x = a, where a is the x-coordinate of a point that lies on the line
- All x-coordinates of the points lie on a vertical line equal
Let us solve the question
∵ The line is parallel to the y-axis
∵ The y-axis is a vertical line
→ By using the second note above
∴ The slope of the y-axis is undefined
→ By using the first note above
∴ The slope of the line is undefined
→ By using the third note above
∵ The equation of the vertical line is x = a
∵ a is the x-coordinate of a point on the line
∵ The line passes through the point (9, -1)
∴ a = 9
∴ The equation of the line is x = 9
Fourth test mark should be 86
85 + 82 + 75 + 86 = 328
328 divide by 4 (as there are four tests) = 82
Answer:
y = 15/x
Step-by-step explanation:
An inverse proportion has the equation ...
y = k(1/x) . . . . k is the constant of proportionality
__
Solving for k, we find ...
k = xy
The coordinates of the given point can be used to find k:
k = (3)(5) = 15
Then the equation of the graph is ...
y = 15/x
