how would i graph y=-x+4

r u serious?

Answer 3

Answer 4

pick a 2 different x-values. Any two will work.

Take each x-value and plug them in to the equation. You'll get a corresponding y-value for each x-value. Now, you'll have two points. Mark each point on your graph. Now get a ruler and connect the two dots. Now you've got your line.

Answer 5

ddx27, we all had to learn how to graph at some point.

Answer 6

thank you brinethery

Answer 7

Start from y = 4 mark as first point
go down 1 unit, then go right 1 unit to get another point
Connect 2 points together to get the line!

Answer 8

This might be a bit more terminology than you need, but a line is "continuous" meaning that you'll have every single x-value under the sun. Also, since it's a function, you'll have only ONE specific y-value for each x-value. That might help you understand why you can pick ANY two x-values and then plot your line.

Answer 9

so I'll pick x=0 and x=1.

y=-(0) + 4
y=4

So the first point is (0,4).

y=-(1)+4
y=3

so the second point is (1,3).
