Not sure what to exactly do from here, as nothing has helped online. Not very good with for loops. Whenever doing this code (as shown) it deletes whatever amount of negatives I have from the start, rather than deleting the actual negative numbers.
Please keep and mind I must use a for loop and input display when doing this. Thank you.

Next time, post the code instead of a screen shot - it makes it easy for us to solve your issue via copy and paste. Use the {} code button to make it neat like this:
function y = displayVector

Since you need a loop, consider creating a logical index matrix and then changing this where the negative numbers are. After the loop, delete the negative number from y.
function y = displayVector
y = input('Display vector: ');
DelIdx = zeros(1, numel(y), 'logical');
for k = 1:numel(y)
if y(k) < 0
DelIdx(k) = 1;
end
end
y(DelIdx) = [];
