to find the slope from a graph you pick two points on the line and determine their coordinates then you determine how much you rise and how much you run (for example you have the points (-2,1) and (3,3) so you start at (-2,1) and from there you go up 2 and over 5 so your slope would be 2/5 .
to find the slope from a table you have to find the rate of change so say your table x values are 0, 1,2,3,4 and your y values are 15,10,5,0,-5 so you have to see how much you have to add or subtract to get to your next value so 0 to 1 you add 1 and 1 to 2 to add 1 and 2 to 3 you add 1 and so on so all your x values changed in +1 on your y values to you have to add or subtract to get to the next value so 15 to 10 you have to subtract 5 10 to 5 you have to subtract 5 then 5 to 0 you have to subtract 5 and so on so all your y values are -5 so your slope will be -5/1 or -5
to find the slope from two points all you have to do is chose 2 coordinates on the (x,y) and (x,y) then you do y2-y1 (y2 just means the second y you chose and y1 means the first y you chose) so you take y2-y1 and divide it by x2-x1 so say your x values are 1,2,3 and your y values are 4,8,12 you can pick any two points so i am picking (1,4) and (3,12) so you do 12-4 divides by 3-1 so 12-4 is 8 and 3-1 is 2 so your fraction is 8/2 but it can be simplified so 8/2 and 2/2 is 4/1 and your slope will be 4/1
SORRY IF THIS IS SO MUCH OR HARD TO READ I TRIED TO GET EVERYTHING AND MADE SURE TO EXPLAIN AND GIVE AN EXAMPLE HOPE THIS HELPS!! DONT SLACK ON YOUR WORK NO MORE!! GET IT DONE IN TIME!! have a great day tho ! if you need help on anything i said comment and i will reply!
