how do i graph this equation?

Question

y=-1/2x+3 .......... -1/2 is a fraction ..... and i need to points that go thru that line....i am stuck ...

Answer 1

It's been a while, but you set x to 0 and get y = 3, and if you set y to zero, you get x = 1 1/2.

That should do it.

Answer 2

the other answers are very good and are based on understanding how the equation of a line works

if you aren't really there yet and you just want to generate some points to graph, just use values of x that are multiples of 2 (like 2,4,6, and 8)

so, for x=2, y=-1/2 * 2 +3 = -1 + 3 = 2, giving point pair (2,2) or x=2, y=2

any multiple of 2 multiplied by -1/2 will give you an integer to easily graph

Answer 3

you would start at 0,3
go down 1 (because the 1 is negative) and over to the right 2 (b/c it is positive)
just continue this pattern and you will be fine
do the opposite for the top part of the graph
(up 1 left 2)

Answer 4

-1/2 is the slope of the line. the 3 is the y-intercept.........so find the y axiz. and go up three. put a dot on it. and go down one and over to the right two spaces.......and put another dot there........do this two or three times and then draw a line through it.........ur graph is made!!!!!!!!!
