Final answer:
To represent two sides of a parallelogram given by the equations y = 2x + 1 and y = -x + 3, two equations that can represent the sides are y = 2x + 2 and y = -x + 2.
Step-by-step explanation:
To represent two sides of a parallelogram given by the equations y = 2x + 1 and y = -x + 3, we need to find two lines that have the same slope as these equations. The slope of the first equation is 2, so any line that has a slope of 2 will represent the first side. Similarly, the slope of the second equation is -1, so any line with a slope of -1 will represent the second side.
Two equations that can represent the two sides are y = 2x + 2 and y = -x + 2. These equations have the same slopes as the given equations, but the y-intercepts are adjusted to make sure the lines represent the correct sides of the parallelogram.
