Question 1155051
What is the slope of a line perpendicular to the line whose equation is 12x-9y=135 fully reduce your answer
<pre>Since in this case, just the slope is needed, we need to solve for y, and compare it to the standard linear equation, 
y = mx + b, more specifically, "m."
{{{highlight_green(matrix(4,3, 12x - 9y, "=", 135,
12x - 135, "=", 9y_____9y = 12x - 135,
y, "=", (12/9)x - 135/9,
y, "=", (4/3)x - 135/9))}}}
The slope you're looking for is the negative reciprocal of {{{highlight_green(matrix(1,5, 4/3, ",", which, "is:", - 3/4))}}}
