Question

Line h passes through (8, 5) and (12, 11). Graph the line perpendicular to h that passes through the point (7, 10). What is the slope of the perpendicular line?

Answer 1

the slope of ur line h is\[m _{1}=\frac{ 11-5 }{ 12-8 }=\frac{ 6 }{ 4 }=\frac{ 3 }{ 2 }\]

Answer 2

if the slope of perpendicular line is\[m _{2}\]

Answer 3

then\[m _{1}m _{2}=-1\]

Answer 4

\[\frac{ 3 }{ 2 }m _{2}=-1\]

Answer 5

\[m _{1}=-\frac{ 2 }{ 3 }\]

Answer 6

so the equation of ur perpendicular line is \[y-10=-\frac{ 2 }{ 3 }(x-7)\]

Answer 7

now solve it

Answer 8

so the slope of the perpendicular line is -2/3?
