Question

How do you graph `y=-x+6`?

Answer 1

As below.

Explanation:

`y = -x + 6`

`y = mx + c " is the slope-intercept form"`

`"Slope "= m = -1, "y-intercept "= 6`

`"when " y = 0, x = 6`

`:. "x-intercept "= 6, "y-intercept "= 6`

`"We know two points on the line, viz. " (6,0), (0,6)`

Now we can plot the points on a graph sheet. By joining them, we get the required line.

graph{-x + 6 [-10, 10, -5, 5]}
