Answer:
Explanation:
The equation of the line can be found using the point-slope form:
y - y1 = m (x - x1)
where m is the gradient, (x1, y1) is a point on the line.
For the given information:
m = 3, x1 = -1, y1 = 3
Plugging in the values into the point-slope form:
y - 3 = 3 (x - (-1))
Simplifying the equation:
y = 3x + 6
So, the equation of the line is: y = 3x + 6
