Answer:
y-intercept = -4
Step-by-step explanation:
equation of a line: y=mx+b
two points given are (5, -6.5) and (-12, 2)
first we can easily find value of m or the slope, by using the slope formula. the value of m=-0.5.
formua to find m: 
= -0.5
to find the value of b (the y-intercept), we need to plug in a y and x value, we are given 2 ordered pairs, you can use either one and plug x-value in for x and the y-value in for y.
if i plug in (5, -6.5), my equation looks like this: -6.5=5(-0.5)+b
then you just solve for b and it turns out to be -4.
a) Is the twitch - initial positive twitch or sudden movement, which is what
makes the car jolt into action.
b) is the acceleration - graph shows the acceleration and
deceleration of the car.
c) is the velocity - starts at 0 and increases until the car
travels at its right speed.
d) is the position - assuming that the car is going on only
one direction. This graph is the only one that does not go back to the x-axis.
The reason that 9.6 is rational is because it can be turned into a fraction.
The fraction is 48/5.
Rational numbers are numbers that can be turned into a fraction, while irrational numbers a those who cannot be turned into a fraction.
Think of it like this
-3 means move 3 spaces back (or left)
+4 means move 4 spaces forward (or right)
so, from 0, move 3 spaces left
then move 4 spaces right
end up with 1 space right or +1
