y= -x +1

I have a x and y table.

That is the problem that i need to solve. Could someone help me figure it out asap.

two points on the line could be (2,-1) and (3,-2). to find the slope you can use the equation

m=(y2-y1)/(x2-x1)= (-2-(-1))/(3-2)=(-2+1)/(3-2)= -1/1= -1. to find the x-intercept we let y=0 in

the equation and get x=1. if you want to find the y-intercept you can let x=0 in the equation and

get y=1 as your y-intercept.

I'm not quite sure what you are asking for. But, the slope intercept form is **
y=mx+b**, where **m** is the slope of the line, **b** is the y-intercept, and
**x** and **y** are the respective coordinates for that line. if you are given two points on a line, for example (1,2) and (2,3) you can find the slope intercept form of the line that runs through those points by first finding the slope, using

**m=(y1-y2)/(x1-x2)**

**m=(1-2)/(2-3)=(-1)/(-1)=1**

So in out equation we now have m. Next to find the y-intercept we substitute the slope we found and one of the given points in **y=mx+b,** to yield** 2=1(2)+b**, and solve:

**2=2+b **

**2-2=b**

so** b=0**

and we can now write the equation for the line;

**y=1x+0 **or** y=x**.

## Comments

It looks like you plugged in x from one of your points and y from the other. The y-intercept of the line you postulated is (0,1).
