5. what is an equation for the line with slope and y-intercept 9? (1 point)
y = x
y = 9x
y = x + 9
y = 9x + 

6. what is an equation in slope-intercept form for the line that passes through the points (1, –3) and (3, 1)? (1 point)
y = 3x + 1
y = x – 3
y = 2x + 5
y = 2x – 5

Without multiplying, tell which product is larger and why. 5 × 1/3 or 5 × 2/3 a)5 × 1/3 because 1/3 is less than 2/3 b) 5 × 1/3 because 1/3 is greater than 2/3 c) 5 × 2/3 because 1/3 is less than 23 d) 5 × 23 because 1/3 is greater than 2/3

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).

Six random samples were taken each year for three years. the table shows the inferred population for each type of fish for each year.
