Question

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


a) (-6, 1)
b) (-1, -6)
c) (1, 4)
d) (4, 1)

Answer 1

Use the slope formula to set this up as follows:

\[m = \frac{y_2 - y_1}{x_2-x_1}\]\[-1 = \frac{y + 2}{x+5}\]Then input one of the points until it satisfies the equation

Answer 2

After doing a little manipulation,

I get -7 = x + y

So whichever point adds up to -7 is correct

Answer 3

looks like b

Answer 4

I'm looking over it to understand it. Thank you :]

Answer 5

Good luck with that :D
