Common Mistakes

Swapping x and y in the plot function.

Using the function name 'plot' as an argument.

The plot function needs the x-values as the first argument and y-values as the second. Here, x is the vector for the horizontal axis.

Complete the code to add a title to the plot.

MATLAB

x = 1:5;
y = [2, 4, 6, 8, 10];

💡 Hint

Common Mistakes

Passing a variable instead of a string to title.

Not using quotes around the title text.

The title function needs a string input to set the plot's title. Here, 'My Plot' is the title text.

Fix the error in the code to plot y versus x with red circles.

MATLAB

x = 1:5;
y = [2, 4, 6, 8, 10];
plot(x, y, [1]);

💡 Hint

Common Mistakes

Using a line style without marker symbols.

Using a color code without marker symbols.

The format string 'ro' tells MATLAB to plot red circles. This fixes the error by specifying the correct marker and color.

Fill both blanks to create a plot of y versus x with blue dashed lines and add an x label.

MATLAB

x = 1:5;
y = [2, 4, 6, 8, 10];
plot(x, y, [1]);
xlabel([2]);

💡 Hint

Common Mistakes

Using the wrong color or line style.

Not using quotes around the label text.

The plot uses '--b' for blue dashed lines. The xlabel needs a string for the label, here 'X Axis'.

Fill all three blanks to plot y versus x with green stars, add a title, and label the y-axis.

MATLAB

x = 1:5;
y = [2, 4, 6, 8, 10];
plot(x, y, [1]);
title([2]);
ylabel([3]);

💡 Hint

Common Mistakes

Mixing up x and y labels.

Not using quotes for text labels.

The plot uses 'g*' for green stars. The title and y-axis label need strings: 'My Green Plot' and 'Y Axis'.
