Question

Graph the linear equation. Find three points that solve the equation, then plot on the graph. -y=x+1

Answer 1

(2,1) (0,-1) (-6,7)

Explanation:

Answer 2

The graph in the attached figure

Explanation:

we have

-y=x+1

Find the y-intercept

For x=0

-y=0+1

y=-1

The y-intercept is the point (0,-1)

Find the x-intercept

For y=0

-0=x+1

x=-1

The x-intercept is the point (-1,0)

Find a third point

For x=1

-y=1+1

-y=2

y=-2

The third point is (1,-2)

Plot the three points to graph the linear equation

see the attached figure

Note Remember that to graph the linear equation is sufficient with two points
