Answer:
(a) 3
Step-by-step explanation:
Calculate the slope m of the line given using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0,3) and (x₂, y₂ ) = (3, 2)
m = 
= - 
given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 3 → (a)
Square root 50 does not belong....all of the other numbers are rational numbers. square root 50 is irrational.
This looks super duper hard wish I can solve it out
I can’t really tell uu the answer but I think it’s 5 length long
C4,1 because I solved it and it showed me
