Explanation:
When the points are plotted on a graph, it is easy to see that the slope of AC is -2 and the slope of BC is 1/2. These slope values have a product of -1, so the corresponding line segments are perpendicular to each other.
___
If you have studied vectors, you can find the dot product of AC with BC:
AC = (-5, 3) -(-2, -3) = (-3, 6)
BC = (6, 1) -(-2, -3) = (8, 4)
The dot product is ...
(-3, 6)·(8, 4) = (-3)(8) + (6)(4) = -24+24 = 0
When the dot product of vectors is zero, they are perpendicular.
option D is the correct option
y= 10- 2x
Now, if we take the first value of x i.e 1
then, y= 10-2(1)
= 10-2 = 8 ---------> this value matches with the given value of y
take,x =2
y=10-2(2) = 10-4 = 6--------->this value matches with the given value of y
taking, x = 3
y= 10-2(3) = 10- 6=4-------->this value matches with the given value of y

Step-by-step explanation:
This
Area of triangle = height * base ÷ 2
6 * 10 = 60
60 ÷ 2 = 30
