Question

****************For a 7 grader***************
How do you find slope and y-intercept from a graph and a equation????

Answer 1

its very easy poppreet. but before i just want to know, where ya from???

maybe i am going a little high standard concept cause i don't know how much you have covered in you syllabus till now.

to find slope and intercept, first convert the equation in the form

y = m.x + c

where m = slope and c is the y intercept

from graph, take any two known points on the line. from one point draw a horizontal line and from another point draw a vertical line so that both the line can meet at any point. now you'll have a right angle triangle. from that triangle find tan A, this tan A is the slope of the line. and you will notice y intercept directly by seeing through the graph. the point where the line crosses the y axis. the ordinate of that point will give you the y intercept.

if you feel any difficulty in understanding concepts then ping me at http://www.chatindia.co.in

Answer 2

i am frm india ok? dont u see the preet in my name?

Answer 3

and i do not understand tan A
