Answer:
Step-by-step explanation:x 1/2 p=75 add that by 9
Y-intercept is where the graph intercepts/crosses the y-axis. So where x = 0
f(0) = 2(0) - 3 + 6
f(0) = 0 + 3
f(0) = 3
y intercept is 3
two decimal places, just add zeros
= 3.00
Start at (0,84) as your y-intercept because thats what he starts with. Then make a negative slope decreasing by 2 each time the x value is increased by 1
