please help!!
What is the equation of the line described below written in slope-intercept form?

the line passing through point (4, -1) and perpendicular to the line whose equation is 2x - y - 7 = 0

y = -x + 1
y = x - 1
y = 2x + 1

What is the equation of the line described below written in slope-intercept form?

the line passing through point (2, 4), parallel to the line whose equation is y = x

y = -x
y = x + 2
y = -x + 2

hey it is quite simple like i told you to

nirmalnema · Answer

FOR the 1 
use one point form..
y-y1=m(x-x1)

nirmalnema · Answer

the product of slopes of two different lines are-1

i think you either made a mistake with your options or with the first question?!?!

anonymous · Answer

second one second option 
the fasted way to solve these problems (if there are no parabolas )then just directly plug in the values of x and y in the equations which you have to see which one matches
