If the matrix size decreases, the number of pixels within the image will what?

Explanation:
Pixel count is determined by the image matrix: rows times columns. When the matrix size decreases, you have fewer locations to sample, so the total number of pixels falls. For example, going from 1024×1024 to 512×512 drops from about 1,048,576 pixels to 262,144 pixels—a quarter as many. This also means lower spatial resolution if the field of view stays the same, since each pixel now represents a larger area on the patient.
