Okay so. My HW says:
The points are (k, 4k), (k+2, 3k)
In point-slope form, give the value of k so that the line that passes through the given points has a slope of -1.
Please show me step by step, please! Thanks!

The formula for slope is Y2-Y1 divided by X2-X1
so we have -1 is equal to 4k - 3k divided by k -(k+ 2)
can you solve for k by collecting like terms?
