The correct answer is y=-\frac{4}{3}x+2.
Explicação
## Step 1
The is y=\frac{3}{4}x+6. The slope of this line is \frac{3}{4}.
## Step 2
The slope of a line perpendicular to a given line is the negative reciprocal of the slope of the given line. Therefore, the slope of the line perpendicular to the given line is -\frac{4}{3}.
## Step 3
The equation of a line in slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
## Step 4
We know that the line passes through the point (3,-2). Substituting these values into the equation, we get -2=-\frac{4}{3}*3+b.
## Step 5
Solving for b, we get b=2.
## Step 6
Therefore, the equation of the line that passes through (3,-2) and is perpendicular to y=\frac{3}{4}x+6 is y=-\frac{4}{3}x+2.
