SOLUTION: which equation describes the line that passes through the point (4,-2) and is perpendicular to the line 4x-7y=28

Question 538744: which equation describes the line that passes through the point (4,-2) and is perpendicular to the line 4x-7y=28
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
---> ---> shows the slope of the line is 4.
The perpendicular line has a slope of .
The point-slope form of the perpendicular line through (4, -2) written using point (4, -2) and slope -1/4 is
or
There are as many point-slope forms as points in a line (infinity), but there is only one slope-intercept form of the equation, starting with "y=" and that is:
