Question 1037971: 1)line l passes through point (9,1) and line p is the graph 3x-7y=22. If l 1p, what is the slope intercept form equation of l?
2) write the equation of the line that passes through points (2,2) and (2,0).
3)complete the slope intercept form equation of the line with slope 4/5 that passes through point (-20,8).

(1)
If WHAT?
Line p has slope , and any line parallel to line p also has slope .
If line 1 is parallel to p, then equation is .

(3)
Similar to number 1. You can start with point-slope form as done there, and solve for y.

(2)
You do this one. Two points. Find the slope. Use either given point and use in point-slope form, or you can do the whole thing from slope-intercept form. y=mx+b, b=y-mx.
Do you notice something that allows you to identify value of slope without any computation?
