Question

Find the equation for the following: Passing the points A(3,0) and B(-2,-3). What are the steps to finding the answer?

Answer 1

is it linear?

Answer 2

It doesn't specify.

Answer 3

first find the slope I guess
by using this formula m=y2-y1/x2-x1

Answer 4

okay so 3/5.

Answer 5

use this m value and the coordinate of any of these points and substitute them in this equation : y=mx+b

Answer 6

to get b

Answer 7

then write the equation y=mx+b using the values you found for b and m

Answer 8

would the final answer be y=3/5x-9/5

Answer 9

yeah you can multiply both sides by 5 to get rid of the denominator

Answer 10

and you can rearrange the equation to have all on one side like this : 3x-5y-9=0

Answer 11

yeah that makes it look better, thank you for all your help :)

Answer 12

you can check your answer by substituting one of the points in the equation just to make sure

Answer 13

you are welcome
