Slope-intercept form.
Slope intercept form is y = mx + b, m is slope and b is y-intercept.
the "steepness" is m
and the "point where the line crosses the y-axis" is the y-intercept, which is "b" value.
Answer:
(-25) + (-45) + (-75)
-145
Step-by-step explanation:
Given that :
jan made withdrawals of 25 45 75 from her savings account
Sum of negative integers to show Jan's withdrawals :
Expression to showing sun of negative integers to represent Jan's withdrawals :
(-25) + (-45) + (-75)
The result of the sum will give the total amount of Jan's withdrawal.
(-25) + (-45) + (-75) = - 145
Hence, total amount Jan withdrew is - 145

Answer:
The unit rate is 20.8 ft/ sec.
Step-by-step explanation:
It is given that the displacement of 644.8 ft in 31 s.
When the rate is define in the quantity of 1, then it is called unit rate.
In 31 s the displacement is 644.8 ft.
Divide both sides by 31,
For one second the value of the displacement is 20.8.
Therefore the unit rate for 644.8 ft in 31 s is 20.8 ft/sec.
