Addition should be the answer to your question
The top answer on your screen is the answer. Hope this help
Since the slope is -2, then m=-2. Since the y-intercept is 5, b=5. Then, we can create the equation: y=-2x+5
Since the slope is
, then m=
. Since the y-intercept is -3, b=-3.
Then, we can create the equation: y=
x-3
