A relation is a function, if and only if, the x- values do not repeat in a given set.
The formula foh slope is y1-y2/x1-x2 , therefore , the slope is 6
We have to translate the coordinates using the given rule.
The given rule is (x-4,y+3)
Now we have to translate the point A(4,6) using the given rule.
Then,
A' is (4-4,6+3)=(0,9)
Now the point B(-2,3) is to be transformed.
Then,
B' is (-2-4,3+3)=(-6,6)
Hence the answer is A'(0,9) and B'(-6,6)
5x+4y = 73
-4x + 4y = -8
5x + 4y -(-4x+4y) = 73 -(-8)
5x + 4y + 4x - 4y = 81
5x + 4x + 4y - 4y = 81
9x = 81
x = 81÷9
x = 9
Substitute x = 9 into any of the equations to find y.
5(9) + 4y = 73
45 + 4y = 73
4y = 73 - 45
4y = 28
y = 28÷4
y=7
Answers :
x = 9
y = 7
One foot is 12 inches so 36/12=3 so 3 feet
