💡 Hint

Common Mistakes

Using 'g*-' which is solid line, not dotted.

Using 'g-:' which places line style before marker, incorrect order.

'g*:' correctly specifies green star markers with dotted lines.

4fill in blank

💡 Hint

Common Mistakes

Using 'o' instead of '+' for markers.

Mixing up line style symbols like '--' instead of '-.'.

'm+' specifies magenta color and plus markers, '-.' is dash-dot line style.

5fill in blank

hard

Fill all three blanks to plot black square markers with dotted lines and label the plot.

MATLAB

plot(x, y, '[1][2]');
title('[3]');

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using '.' which is point marker instead of 's:' for square markers with dotted lines.

Forgetting to put the title string in quotes.

'k' is black color, 's:' is square marker with dotted lines, and the title is set to 'My Plot'.
