Final answer:
The two lines have different slopes, with the first line having a slope of -2 and the second line having a slope of 2. Since the slopes are different, the two lines intersect at exactly one point, indicating that there is one solution.
Step-by-step explanation:
To determine if two lines have no solution, one solution, or an infinite number of solutions, we need to find the slopes of each line. If the slopes are different, the lines intersect at one point, indicating one solution. If the slopes are the same, but they have different y-intercepts, the lines are parallel and there is no solution. If the slopes and y-intercepts are the same, the lines coincide and there are an infinite number of solutions.
For the first line through (-1,3) and (0,1), the slope can be calculated using the formula slope (m) = (y2 - y1) / (x2 - x1). Plugging in the values, we get:
m = (1 - 3) / (0 + 1) = -2
The second line passes through (1,4) and (0,2). Using the same formula:
m = (2 - 4) / (0 - 1) = 2
Since the slopes of the two lines are different, they will intersect at exactly one point, indicating one solution.
