Answer:
Not giving you answers, but I'll try to help you find a slope
Explanation:
So take the first question.
A slope equals rise/run. The first point is 2,1 and the second is 0,-3.
For rise, take the second numbers you see for each written point (so 1 and -3). Subtract them. For run, take the first 2 numbers (2 and 0)
1--3 is 4
2-0 is 2
So the slope is 4/2 (write it like you would a fraction, 4 over 2). If I messed up, sorry. I don't know much about this yet either.
