Answer:

y = -x - 1

Explanation:

1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. To find the slope given two points, we can use the formula
(y_2-y_1)/(x_2-x_1) and plug in the corresponding variable.


  • (5-(-2))/(-6-1)

  • (5+2)/(-7)

  • (7)/(-7)

  • -1

3. Okay, so the slope is -1x or just -x. This means that the equation looks like this so far: y = -x + b

4. To find b, the y-intercept, we can take the equation of
b = y_1 - m * x_1 and plug in the values!


  • b = -2-(-1)*1

  • b = -2 + 1 * 1

  • b = -1 * 1

  • b = -1

5. Now that we have our y-intercept and slope, let's plug in those values and find the equation!


  • y = -x - 1

Therefore, the equation of the line is y = -x - 1. I hope this helped you!
