Question

Write the standard form of the line that passes through the given points. (7, -3) and (4, -8)

Answer 1

y=mx+c is the standard equation of a straight line

to get this you must work out the y intercept, and the gradient

the gradient of a line passing through two coordinates is the difference in y ordinates divided by the difference in x coordinates
labelling the first set of coordinates to be (x1, y1) and the second set (x2, y2)
the gradient would be equal to (y2-y1)/(x2-x1)
so m=(y2-y1)/(x2-x1)

next to get the equation of a line you use the formula

y-y1=m(x-x1)

where y1 is the y ordinate of one of the two coordinate sets, which ever one you choose, you must use the same set for the x ordinate for example
if i did y-(-3) i would have to use 7 for the x1 to be consistent

can you work out the answer? I will confirm if you are correct, or help along the way

Answer 2

???

Answer 3

labelling the first set of coordinates to be (x1, y1) and the second set (x2, y2)
(x1,y1)= (7, -3)
(x2,y2)= (4, -8)

now work it out

Answer 4

And that will be in standard form?

Answer 5

you have to work it out, i am not going to give you the answer

Answer 6

I'll get it, don't worry..lol
