1) 1, -2..for the first question
perp to x-3y=2 thru (2,4)
For perpendicular we swap the coefficients on x and y, negating one
3x + y = some constant
We get the constant in the obvious way from the point
3x + y = 3(2) + 4 = 6 + 4 = 10
Answer: 3x + y = 10
False
on the left, there is 2 negatives, which cannot result in a negative number on the right
Answer: r and s because these are the lines that 1 and 9 are on
