Answer:
y = -3/4x + 14
Step-by-step explanation:
y = 4/3x+ 7...slope here is 4/3. A perpendicular will have a negative reciprocal slope. All that means is flip the slope and change the sign.
4/3....flip it....3/4....change the sign....-3/4. So our perpendicular equation has to have a slope of -3/4
y = mx + b
slope(m) = -3/4
(4,11)...x = 4 and y = 11
now we sub and find b, the y int
11 = -3/4(4) + b
11 = - 3 + b
11 + 3 = b
14 = b
so ur line is : y = -3/4x + 14 <===
