The correct answer is: y=3/2x-11 :D



Answer:

[tex]y=\frac{3}{2}x-11[/tex]

Step-by-step explanation:

We have been given an equation [tex]y=-\frac{2}{3}x+5[/tex]. We are asked to find the equation of line perpendicular to our given equation and passes through point (8,1).

We know that the slope of a perpendicular line to a given line is negative reciprocal of the slope of given line. So the slope of perpendicular line to the line [tex]y=-\frac{2}{3}x+5[/tex] will be negative reciprocal of [tex]-\frac{2}{3}[/tex].

[tex]\text{negative reciprocal of }-\frac{2}{3}=-(-\frac{3}{2})[/tex]

[tex]\text{negative reciprocal of }-\frac{2}{3}=\frac{3}{2}[/tex]

Upon substituting [tex]m=\frac{3}{2}[/tex] and coordinates of point (8,1) in slope intercept form of equation we will get,

[tex]1=\frac{3}{2}*8+b[/tex]

[tex]1=3*4+b[/tex]

[tex]1=12+b[/tex]

[tex]1-12=12-12+b[/tex]

[tex]-11=b[/tex]

Therefore, the equation [tex]y=\frac{3}{2}x-11[/tex] represents the equation of line perpendicular to our given line.
