# What is the slope and intercept for #x - y + 1 = 0# and how would you graph it?

##### 1 Answer

Slope:

y-intercept:

x-intercept:

#### Explanation:

The general slope-intercept form for a line is

can be converted into slope-intercept form by

adding

Based on the general form we can see that

and

Assuming the x-intercept is also required,

we note that the x-intercept is the value of

The x and y-intercepts give us the points

If we plot these two points on the Cartesian plane and draw a straight line through them, we will obtain the required graph

graph{(x-y+1)((sqrt(x^2+(y-1)^2))-0.1)((sqrt((x+1)^2+y^2))-0.1)=0 [-5.25, 5.85, -2.02, 3.527]}
