Answer:
v=10.1
Step-by-step explanation:
v= 4.5 + at -------> equation 1
given
a=1.6
t=3.5
so we will plug in the value in equation 1
v = 4.5 + (1.6 x 3.5)
v = 4.5 + 5.6
v = 10.1
okay so you would go down to -8, then the slope would be 4/1 which means to go up four and then over one. then you have the line.
i hope this helps you!
