Question

to draw the graph ofx-y=4 find y when x=5​

Answer 1

Let's put this into slope-intercept form to make graphing easier. The general equation for that form is:

y = mx + b

where m is the slope and b is the y-intercept. So we'll get:

x + y = 4

y = −x + 4

The y-intercept is 4, so that's a point

(0,4) .

The slope is

−1

, so the graph will move one point down for every point it moves right. The next point we can graph is

(1,3)

. Use a straightedge to connect those two dots and make the graph. It'll look like this:

graph{-x+4 [-10, 10, -5, 5]}
