Question! Can someone look at this screenshot for me and help!? Explain how you found your answer.

hartnn (hartnn):

u know how to find equation of line when 2 points are given ?

hartnn (hartnn):

that is slope :) m=4/5 the equation will be y=mx+c y=(4/5)x+c now put any point say (x,y)=(4,6) in this and find c can u ?

hartnn (hartnn):

any point from (-1,2) and (4,6) so i chose (4,6) ..... (4,6) is one point only, not 2. when i put that in y = (4/5)x + c i get 6=(4/5)*4 +c now find c from here.

hartnn (hartnn):

good. so the equation of your line will be y=(4/5)x+14/5 or multiplying 5 on both sides, we get. 5y=4x+14. ok?

hartnn (hartnn):

can u spot the point (4,6) in graph ?

hartnn (hartnn):

good work :) both are correct... now to graph the line , just join these two points with a straight line.....

hartnn (hartnn):

yes! both of them.

hartnn (hartnn):

thats it :)

hartnn (hartnn):

yup, done. welcome :)
