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 dram 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.
