Answer : The correct option is, (A) -3
Step-by-step explanation :
The general form for the formation of a linear equation is:
where,
x and y are the coordinates of x-axis and y-axis respectively.
m is slope of line.
Now we have to calculate the slope of line.
Formula used :
Here,
and
m = -3
Therefore, the slope of the line is, -3
Answer: D) reflection across y = -x
Explanation:
When we reflect over y = x, we basically swap x and y. So for instance, the point (3,1) becomes (1,3).
When reflecting over y = -x, we will do the same thing but we'll make each coordinate swap in sign from positive to negative (or vice versa). The rule for reflecting over y = -x is
So if we apply that rule to point A(3,1) then it becomes A ' (-1, -3).
Similarly, B(1,5) moves to B ' (-5, -1)
Finally, C(6,9) becomes C ' (-9, -6)
