Answer:
(a)As time increases, the number of flyer Dale has increases.
The rate is 3 flyers per minute.
(b)62 flyers
Explanation:
(a)To determine the rate at which the number of flyers increases or decreases, we pick two pairs of points from the table.
(10, 92) and (15, 107)
[tex]\begin{gathered} \text{Slope}=\frac{107-92}{15-10} \\ =\frac{15}{5} \\ =3 \end{gathered}[/tex]
The rate at which the flyers are printed is Increasing at a rate of 3 flyers per minute.
(b)To determine how many flyers Dale has at the beginning, we find the equation of the line.
The slope-intercept form of a line is y=mx+b.
Substituting the point (10,92) in the slope-point form, we have:
[tex]\begin{gathered} y-y_1=m(x-x_1) \\ y-92=3(x-10) \\ y=3x-30+92 \\ y=3x+62 \end{gathered}[/tex]
The y-intercept of the line, b=62.
Therefore, Dale already had 62 flyers when he started printing.
