How can I visualize my data features to check if it linear or not?

If I have data like this:
x_train = np.array([[2104, 5, 1, 45], [1416, 3, 2, 40], [852, 2, 1, 35]])
y_train = np.array([460, 232, 178])

Can I plot my data features using matplotlib to check my hypothesis before I start developing my model?

You can plot aspects of your data.

But you don’t have a hypothesis until after you have completed training. That’s when you have
a model.

However, plotting a data set with four features isn’t possible. Your human vision system only works in 3D.

Yes you can do this by visualization also as well by performing the Hypothesis Testing also.
