Final answer:
The equation cannot be determined without the slope.
Step-by-step explanation:
The equation of a line passing through the point (-3,1) can be found using the point-slope form of a linear equation. The point-slope form is given by y - y1 = m(x - x1), where (x1, y1) are the coordinates of the given point and m is the slope of the line. Since we only have one point, we need the slope of the line to find the equation.
To determine the slope, we can use another point on the line. Let's say the line passes through the point (x2, y2). The slope is then given by m = (y2 - y1) / (x2 - x1). Since we don't have another point, we can't determine the slope and therefore cannot find the equation of the line passing through (-3,1).
