Question

Graph the line

4/3 x
how to find points?

Answer 1

Graph y = 4/3x first.

Answer 2

To graph a line, you need two points.

y = 4/3 * x

Let x = 0, and x = 1, find y for each.

(0,y) and (1,y)

Answer 3

how do i do that?

Answer 4

If x=0,
y = 4/3 * 0 = 0

The first point is x=0, y=0 (x,y) = (0,0)

Answer 5

if x=1, y=(4/3)* 1 = 4/3

(x,y) = (1, 4/3)


there you have 2 points, plot them and draw a line through both points.

Answer 6

Thanks. but how about problems like y=-x?

Answer 7

It is the same for any linear equation. You just need to find 2 points to graph a line.

For y=-x

For x=0, y=0 (0,0)
For x=1, y=-1 (1,-1)

Answer 8

thanks
