Question

Name the point where the lines intersect.
y=-x-1
or
x-y=-5

Answer 1

Answer:

(-3,2)

Step-by-step explanation:

It would be easier and more helpful of you have graph paper because I turn the equations to slope intercept form. It makes it easier because you can visually see where the points intersect.

y=-x-1 is already in slope intercept form so you don't have to change it, just graph it.

-1 is your y-intercept so you can put a point there, and your slope would be -1, which means your slope would be going from the upper left corner to the bottom right corner.

You would go down one and move to the right/left one.

x-y=-5 is in standard form so you would have to change it.

For this one, first find the slope.

Slope for standard form is -A/B so in this case it would be -x/-y which is equal to x/y. Your slope would be 1.

Slope intercept form is y=mx+b

So from what we have now, so far it would look like y=x

In the end, it would be y=x+5

I just changed the signs from -5 to make it positive 5

So now you could just graph both equations, y=-x-1 and y=x+5.

When you graph it, you would see that both lines intersect at (-3,2)
