slope is -1

we have a point as (-4,3)
we can use slope intercept form of line

we can plug m=-1

now, we can plug point (-4,3)
x=-4 and y=3 and then we can find b


now, we can plug back
and we get

Answer:
168.4953 (m/s)
Step-by-step explanation:
a(t)=x''(t)=(0.0951t⁴-0.101t³+0.837t²+3.87t-9.37)''= =4*3*0.951t²-3*2*0.101t+2*0.837 =11.412t²-0.606t+1.674.
a(3.85)=11.412*3.85²-0.606*3.85+1.674=168.4953
