Equation of a line:
, where m is the slope and c is the y-intercept. To calculate the slope, we do so using the formula: ![m = \frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D)
Now plugging in our values, ![m = \frac{4 - (-3)}{-7 - (-2)} = \frac{4 + 3}{-7 + 2} = \frac{7}{-5} = \frac{-7}{5}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B4%20-%20%28-3%29%7D%7B-7%20-%20%28-2%29%7D%20%20%3D%20%5Cfrac%7B4%20%2B%203%7D%7B-7%20%2B%202%7D%20%3D%20%5Cfrac%7B7%7D%7B-5%7D%20%3D%20%5Cfrac%7B-7%7D%7B5%7D)
So our slope m, is = -7/5
We can now input the value of the slope. But in this question, we cannot use the above equation of a line since we are asked to use a point-slope equation expression, so the equation is ![y - y1 = m(x - x1)](https://tex.z-dn.net/?f=y%20-%20y1%20%3D%20m%28x%20-%20x1%29)
Now we plug in our values,
![y - (-3) = \frac{-7}{5}(x - (-2))\\y + 3 = \frac{-7}{5}(x + 2)](https://tex.z-dn.net/?f=y%20-%20%28-3%29%20%3D%20%5Cfrac%7B-7%7D%7B5%7D%28x%20-%20%20%28-2%29%29%5C%5Cy%20%2B%203%20%3D%20%5Cfrac%7B-7%7D%7B5%7D%28x%20%2B%202%29)
So the answer should be option D.
