Answer:

y + 4 = -3/2(x + 4)

Explanation:

The general equation for the point-slope form is given by:

(y - y1) = m(x - x1), where

  • m is the slope,
  • and (x1, y1) is one point on the line.

Step 1: Find m, the slope:

We can find the slope using the slope formula, which is given by:

m = (y2 - y1) / (x2 - x1), where

  • m is the slope,
  • (x1, y1) is one point on the line,
  • and (x2, y2) is another point on the line.

Thus, we can plug in (-4, -4) for (x1, y1) and (-2, -7) for (x2, y2) in the slope formula to find m, the slope of the line:

m = (-7 - (-4)) / (-2 - (-4))

m = (-7 + 4) / (-2 + 4)

m = -3/2

Thus, the slope of the line is -3/2.

Step 2:

Let's use (-4, -4) as our (x1, y1) point in the point-slope form:

y - (-4)) = -3/2(x - (-4))

y + 4 = -3/2(x + 4)
