Answer:
21.3 cm
Step-by-step explanation:
first find the rate of change (RISE/RUN)
[tex]\frac{19.8-25.2}{24-6}[/tex] which gives you -0.3
Next, create an equation. You can choose any point, but I chose (6,25.2) because it is given.
y - 25.2 = -0.3(x-6)
y - 25.2 = -0.3x + 1.8
y = -0.3x + 27
Finally, plug in 19 for x...
y = -0.3(19) + 27 = 21.3 cm
