Look at the paper for solutions.
Answer:
4
Step-by-step explanation:
For WX to be perpendicular to YZ, then the product of their slope must be -1
For slope of WX
W(2-3) and X(-4.9),
Mwx = 9-(-3)/-4-2
Mwx = 12/-6
Mwx = -2
For slope of Y(5. y), and Z(-1, 1),
Myz = 1-y/-1-5
Myz = 1-y/-6
Since Mwx•Myz = -1
-2•(1-y/-6) = -1
1-y/3 = -1
1-y = -3
-y = -3-1
-y = -4
y = 4
Hence the value of y is 4
