From Point (-2,2), we go to point (0,1). The x changed by two, and the y changed by one. Therefore, when x changes by one, y changes by one-half. This slope is negative, making the answer -1/2
Assume that the other number is y. we know that the addition of both number is -9 this means that: x+y=-9 reorder this equation to seperate the y variable: y=-9-x
In using a linear function, follow the pattern y=mx + b. In this scenario, the m (which represents slope) is -10 since $10 is taken away every time. The b(which represents y-int) is 190 because you start with 190 (x=0)
