Answer:
Option C is right answer
Step-by-step explanation:
We have in coordinate geometry a straight line in slope intercept form as
y = mx+c
where m is the slope and c is the y intercept
There are special lines when m=0 and m = infinity.
When a line is parallel to y axis, it has slope = tan90 = infinity.
Hence line will have equation of the form x = a for some a.
Since the line passes through (3,2) we can find a using this.
Substitute x value to get 3 = x
Hence equation of the line is x =3
Answer:
600 units squared
Step-by-step explanation:
Answer:
-7.78 ,-7, -7
Step-by-step explanation:
Convert the two fractions into decimals
-7 = -7.65
-7 = -7.17
The answer is 10 because 45-9 is 36, so 46-x must be 36, which would result in 10
Answer:
(2, - 5)
Explanation:
The line y = -1 is horizontal: parallel to the y-axis.
The point B (2,3) is above the line y = - 1 at a distance equal to the y-coordinate of B (y = 3) less - 1:
Δy = 3 - ( - 1) = 4
When the point B (2,3) is reflected over the line y = -1, the x-coordinate does not change. The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.
Hence, the coordinates of the vertex B' are x = 2, y = - 5: (2, - 5).
