Rule 1: Parallel lines have equal slopes.
Your given equation is in slope-intercept form , so you can tell by inspection that the slope of the given line is 7.
Next you need to use the point-slope form of the line to find the desired equation. The equation of a line with slope passing through point (,) is , so just substitute the values you know, namely the slope, and the coordinates of the given point: (,) = (,).
You should rearrange by solving for y to put your equation for the desired line into slope-intercept form to match the given equation. I'll leave that as an exercise for the student.

I need to find an equation of the line that is parallel to the line y=7x-3 and passes thru the point (8,7).
.
okay, of line is . Since the line are parallel, .
Therefore, thru point (8,7), we can get the y-intercept via Slope-intercept Form:
----->, y-intercept.
Then, line eqn is----->, or Standard Form
We see the graph:
-------> RED, Line ; GREEN, Line
Thank you,

find an equation of the line that is parallel to the line y=7x-3 and passes thru the point (8,7).
------------------
If parallel to y = 7x-3, the slope is 7
---------------------
Form: y = mx + b
7 = 7*8 + b
7 = 56 + b
b = -49
---------
Equation:
y = 7x - 49

If the lines are parallel it means that they have same slope.
The basic form of line y=mx+b m is a slope, then y=7x-3 slope m =7
Using "point-slope" form of the line y-y1=m(x-x1) you can find equation of the line passing through the point (x1,y1)----(8,7)
y-7=7(x-8)
y=7x-49-----answer

Parallel lines have identical slopes.
The slope of your new line is identical to the old line,
Use the point-slope form of the line,
where and ,
.

Here are both lines graphed, along with point (8,7), as visual proof of the solution.
