Answer:
The perpendicular equation is y = 4/3x
Explanation:
To find the equation perpendicular to this, we first need to look at the slope of the original line, which is -3/4. Perpendicular lines have opposite and reciprocal slopes, meaning that the new line would have 4/3 slope. Now we can use this and the point in point-slope form to get the final equation.
y - y1 = m(x - x1)
y - 12 = 4/3(x - 9)
y - 12 = 4/3x - 12
y = 4/3x
