Answer:
y = 3x + 6
Step-by-step explanation:
The general equation of a line is;
y = mx + b
where m is the slope and b is the y intercept
The slope of the first line is -1/3
when two lines are perpendicular, the product of their slopes is equal to -1
Thus;
-1/3 * m2 = -1
-m2 = -3
m2 = 3
So the equation of the second line is;
y = 3x + b
To get b, we substitute the coordinates of the point (-1,3)
We substitute -1 for x and 3 for y
so, we have;
3 = 3(-1) + b
3 = -3 + b
b = 3 + 3
b = 6
So we have the second equation as;
y = 3x + 6
