1) Find an equation of the line that passes through thr pair of points (-5,-9) and (2,-7).

1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is $m=\frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }$ , so in this case, it is $m=\frac{ (-7) - (-9) }{ 2 - (-5) }$ , which comes to $\frac{2}{7}$ . Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y= $\frac{2}{7}$ x- $\frac{53}{7}$ .

2. Use the same process as in question 1 to find:
y=-7x+11

$\dfrac{4 \textrm{ cm}}{\textrm{year}} \times \dfrac{\textrm{year}}{365 \textrm{ days}} \times \dfrac{10\textrm{ mm}}{\textrm{cm}} = \dfrac{8}{73} \approx 0.1 \textrm{ mm per day}$
