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
To make this equation have infinitely many solutions, we want to end up with the equation x=x. With this equation, no matter what number we plug in for x, it will be a solution since it will equal itself.
-(x-8)+4x=2()+x
-x+8+4x=2()+x
-2x+8+4x=2()
2x+8=2()
x+4=()
Therefore if we plug x+4 into the equation we will find our equation with infinitely many solutions.
-(x-8)+4x=2(x+4)+x
We can check our solution:
-(x-8)+4x=2(x+4)+x
-x+8+4x=2x+8+x
3x+8=3x+8
Since the right and left side of the equation our equal, we know our solution works.
Answer:15
Step-by-step explanation:The formula for volume of a square pyramid is A^2 * h/3 with A being base side length and h being height, so just plug in 3 for a and 5 for h, getting you (3)^2 * 5/3, then 9* (5/3) then 45/3 then 15
