The answer is C the whole shape it a rectangle the two triangles in it are going to be congruent.
Answer:
y = -5 × 1 + 2
Step-by-step explanation:
- y = y, m = slope, x = x point given (1), b = y point given, unless a zero (2)
- Formula - y = mx + b
- Plug it in
- y = -5 × 1 + 2
Triangle ABC is a right angle triangle. The point of circumcentre and the point of orthocentre is the same point, as shown in the diagram below. The coordinate of the point is (2.5, 2.5)
Answer:
(C) A'(4, 1)
Step-by-step explanation:
When a point is reflected across the x-axis, the following happens
- The x-coordinate remains the same
- The y-coordinate is transformed into its opposite (its sign is changed).
Given the Point A(4, –1)
When it is reflected, following the rules above
- The x-coordinate remains 4
- The y-coordinate changes from -1 to 1.
The coordinates of A' will therefore be: A'(4,1)
-3/4 is rational
