1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is [tex] m=\frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } [/tex], so in this case, it is [tex] m=\frac{ (-7) - (-9) }{ 2 - (-5) } [/tex], which comes to [tex] \frac{2}{7} [/tex]. 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=[tex] \frac{2}{7} [/tex]x-[tex] \frac{53}{7} [/tex].
2. Use the same process as in question 1 to find:
y=-7x+11
