Answer:
Step-by-step explanation:
Equation of the given line:
Slope of the line =
Slope of the perpendicular line =
So the equation of the perpendicular line:
This passes through the point (-1,2).Substituting in the equation:
=>
=>
So the equation of the line :
Answer:
x = 25
Step-by-step explanation:
Given:
Since ∠A is equivalent to ∠B...
Open the parenthesis:
Add 8 both sides:
Simplify both sides:
Subtract 6x both sides:
Simplify both sides:
Explanation:
Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)
Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule . We've added 9 to the x coordinate, and the y coordinate stays the same.
This notation can be shortened to <9, 0>
In general, the notation is shortened to the translation vector notation
. In this case, a = 9 and b = 0.
