How do you determine the equation of a line that has the same y int.
as the line y=8x+6?
Any equation in the form y = mx+6 has a y intercept of 6
:
and is perpendicular to the line 4x+7y-3=0
Put the equation into slope intercept form to find the slope
4x + 7y - 3 = 0
7y = -4x + 3
y = x +
:
Slope relationship between perpendicular lines, m1*m2 = -1
m1 = find m2
* m2 = -1
multiply both sides by
m2 =
:
The equation of the perpendicular line with a y intercept of 6:
y = x + 6
