y=x-9 , (0,0)
Step 1
Use the slope-intercept form to find the slope.

Step 1.1
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Step 1.2
Using the slope-intercept form, the slope is 1.
m=1
m=1
Step 2
To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.
Step 3
Use the slope 1 and a given point (0,0) to substitute for x1 and y1 in the point-slope form y-y1=m(x-x1), which is derived from the slope equation m=y2-y1x2-x1.
y-(0)=1(x-(0))
Step 4
Simplify the equation and keep it in point-slope form.
y+0=1(x+0)
Step 5
Solve for y.

Step 5.2.1
Multiply x+0 by 1.
y=x+0
Step 5.2.2
Add x and 0.
y=x
y=x
y=x
