Which point below would you use with the point (-2, -5) to get a line with a slope of -1? 1. (-6, 1) 2. (-1, -6) 3. (1, 4) 4. (4, 1)

Hello! if you know the formula for finding slope, you know that it is y2 - y1/ x2 - x1, because slope is rise/run. what we can do to find the answer is experiment each answer choice to see what we get. okay. let's start with a. 1 - (-5) is 6 / -6 - (-2) is -4. 6/-4 is -3/2. -3/2 < -1. a is eliminated. let's try b. -6 - (-5) is -1. -1 - (-2) is 1. -1/1 is -1. -1 = -1. score! but wait. let's check the others to make sure. 4 - (-5) is 9. 1 - (-2) is 3. 9/3 is 3. 3 > -1. c is eliminated. 1 - (-5) is 6. 4 - (-2) is 6. 6/6 = 1. 1 > -1. d is elimiated. when you work it out, you see that (-1, -6) is the only point that works. therefore, the answer is b: (-1, -6).
