Question

find the specified intercept for the graph of each equation 2x+9y=-9      x-intercept:    ?

anonymous · Answer

Just make x=0 and you can compute the y-value for that. That is your x-intercept.

so its zero

anonymous · Answer

No I am sorry, I was mistaken above. That will give you the y-intercept. To solve for the x-intercept you have to let y=0;

$$2x+9y=-9$$Where y=0$$2x+9*0=-9$$and now you can divide both sides by 2$$2x=-9$$which would give you$$x = -\frac{ 9 }{ 2 } = -4.5$$ And that is your x-intercept. For your y-intercept just repeat this procedure and make x=0.
