That line is in point-slope form:


\sf y-y_1=m(x-x_1)

Where 'm' is the slope and (x1, y1) is a point on the line.

Perpendicular lines have opposite slopes. To get the opposite, we take the reciprocal and multiply it by -1.


\sf -(2)/(3)

Reciprocal:


\sf -(3)/(2)

Multiply by -1:


\sf(3)/(2)

We can plug this slope and the point into point-slope form, and then convert it to slope-intercept form.


\sf y-y_1=m(x-x_1)


\sf y-(-2)=(3)/(2)(x-(-2))

Negatives cancel out:


\sf y+2=(3)/(2)(x+2)

Distribute 3/2 into the parenthesis:


\sf y+2=(3)/(2)x+(6)/(2)

Simplify the fraction:


\sf y+2=(3)/(2)x+3

Subtract 2 to both sides:


\boxed{\sf y=(3)/(2)x+1}
