Determine whether (-1, -8) is a solution for y=x-5.

T-Table

Hmmmm, Im not sure where to start, but I will try.

X= -1, * 5 = -5

X= 0 * 5=0

X= 1* 5 = 5

X=2*5= 10

X=3* 5= 15

Is this correct? thank you for your help!

The graph?

Hi Abby;

y=x-5

(-1, -8)

Let's plug-in this coordinate...

-8=-1-5

-8 does NOT equal -6

This point is NOT a solution for this equation.

If you want to graph this, the equation is in the format of....

y=mx+b

m is the slope

b is the y-intercept, the value of y when x=0.

slope is 1.

y-intercept is (0,-5)

To graph, you begin with this point, (0,-5), and move up 1 unit while moving to the right 1 unit. You will also move down 1 unit while moving to the left 1 unit.
