In this case the answer is very simple.
To find the solution to the exercise we'll have to carry out several steps.
Step 01:
Data
slope = m = - 1 / 7
point (-5 , 3 ) x1 = -5 y1 = 3
Step 02:
Point-Slope Form of a Straight Line
[tex](y\text{ - y1) = m (x - 1)}[/tex][tex](y\text{ - 3) = }\frac{-1}{7}\cdot(x-(-5))[/tex][tex]\begin{gathered} (y\text{ -3) = }\frac{-1}{7}(x\text{ +5)} \\ (y-3)\text{ = }\frac{-x}{7}\text{ -}\frac{5}{7}\text{ } \\ y\text{ = }\frac{-x}{7}\text{ -}\frac{5}{7}+3 \end{gathered}[/tex][tex]\begin{gathered} y\text{ = }\frac{-x}{7}-\frac{5+21}{7} \\ y\text{ = }\frac{-x}{7}\text{ }+\frac{16}{7} \end{gathered}[/tex]The answer is :
[tex]y\text{ = }\frac{-x}{7}+\frac{16}{7}[/tex]
