Given the following information, write an equation in standard form to represent the specific line that is perpendicular to 2x - 5y = 10 and has the same y-intercept as 3x - 4y = -12.
I need to know the steps.
The standard form is y = mx+b , m= slope , b= y intercept
so
2x-5y = 10
-5y = 10-2x
5y = 2x -10 or
y = (2/5 )x - 2
Slope of this line is 2/5 and y intercept is -2
Line perpendicular to this line will have slope = - 5/2
So equation is
y= -(5/2) x + b
which has y intercept of other line
3x- 4 y = -12
or y = (3/4 )x +3
having y intercept = 3
So the requied equation is
y = - (5/2) x + 3
