Step-by-step explanation:

Hey there!

The given equation is; y= -3/4x+1...........(i)

The equation of a line which passes through point (9,12) is;

(y-y1) = m2(x-x1)

(y-12) = m2(x-9).................(ii)

From equation (i)

y = -3/4x+1

Slope (m1) = -3/4

As per the condition of perpendicular lines;

m1*m2= -1

[tex] - \frac{3}{4} \times m2 = - 1[/tex]

-3m2 = -4

[tex]m2 = \frac{ - 4}{ - 3} [/tex]

Therefore, m2= 4/3.

Putting value of m2 in eqaution (i).

(y-12) = 4/3(x-9)

[tex]y - 12 = \frac{4}{3} x - 9 \times \frac{4}{3} [/tex]

[tex]y = \frac{4}{3} x - 3 + 12[/tex]

Therefore, the equation is; y = 4/3x +9.

Hope it helps...
