If two lines are perpendicular, then their slopes have a product of -1 or you could say they are opposite signed reciprocals of each other.
The given equation has a slope of -3. We know this because it is in slope-intercept form y = mx + b ...y = (slope)x + (y-intercept).
so taking the slope -3...the opposite signed reciprocal would be +

Now we have a slope and a point... we can use them to find the b (y-intercept)
x = 4, y = 3, and m =



Using the common denominator fraction for 3, we subtract 4/3 from both sides


plug the values for m and b into the slope intercept form
<em>Answer:</em>
<em>X = 9</em>
<em>Step-by-step explanation:</em>
<em>X + 12 = 4X - 15</em>
<em>12 + 15 = 4X - X</em>
<em>3X = 27</em>
<em>X = 27 : 3</em>
<em>X = 9</em>
