You can put this solution on YOUR website! find the slope intercept form of a line that is perpendicular to the line
2x-7y=3 and has a x intercept of 4
----
Find the slope of the given line::
7y = 2x-3
---
y = (2/7)x - (3/7)
---
slope = 2/7
-----
Find the slope of the perpendicular line::
Ans -7/2
-----
Find the equation of the perpendicular line::
slope = -7/2 and passes thru (4,0)
----
Form:: y = mx + b
Solve for "b"::
0 = (-7/2)4 + b
0 = -14 + b
b = 14
------
Ans: y = (-7/2)x + 14
