Question

how do you graph y=-x+4, please show both points

Answer 1

what are the coordinates for the second one

Answer 2

i know the first is (0,4)
but whats the second coordinate

Answer 3

just you need give to x two values and calculi the y so than you need graph these two point with coordinates what will get

hope helped

Answer 4

well.. if y=mx+b

and your looking at the linear equation of y=-x+4
Than the y-int is (0,4)
and you can find another point on the graph using the slope
m=change in y over change in x
so the next point would be 1,3 and so forth...

Answer 5

you can also just plug in values for x(input) and see what values of y you get(output)
than graph those

Answer 6

can you also help me graph y=2x-5

Answer 7

@ana.ie.lee
sure!

the y intercept is when x=0 so...
y=2(0)-5
the y-intercept is -5.

Finding a second point on the graph... you can use x=1
when x=1
y=2(1)-5
y= -3

Your two points : (0,-5) and (1,-3)

All you need to do is graph
