Question

What is an equation of the line that passes through the points (2,-3) and (1,0)?

Answer 1

Answer:

If you use y=mx+b you will find that the equation is:

y=-3x+3

Step-by-step explanation:

Answer 2

Answer:

y=-3x+3

Step-by-step explanation:

1: subract one of the y from the other one 0--3, or 0+3=3

2: Do the same with the x of the right y     1-2=-1

3: put the solution to the y over the solution to the x     3/1-

4: simplify    -3

5: write out what you now know     y=-3x+b

6: fill in y and x with one of the points      -3=-3(2)+b

7: Solve

 a) Combine like terms     -3=-6+b

 b) add 6 to both sides    3=b

8: write out the problem with everything you know     y=-3x+3
