first write the equation as y = mx +b the value m is the slope of th eoriginal line all perpendicular lines will have slope = -1/m
btw - I think your answer is incorrect...
y = mx +b=4y=-5x+8
you need to show some work - otherwise you can just guess all 4 until I say... what is the slope of the original line? then - what is the slope of any perpendicular line..?
4y=-5x+8 so y= ??
No I wasn't guessing all 4 -.-, you asked me to rewrite the equation in the formula y = mx +b so i did and i wanted you to take me from there.
cause im kinda confused
Slope is −5/4
but im confused from there..:(
OK so slope of original line is -5/4 and so the slope of any perpendicular line is -1/m -1 /(-5/4) = 4/5 so which of the answer options has a slope of 4/5? (hint - the offset value i.e. the constant number does not affect the slope or answer....)
