Question

Are these lines parallel perpendicular or neither?
Y=-4+3
-2x+8y=5

Answer 1

Noo I im pretty sure

Answer 2

wait

Answer 3

Y=-4+3 where is the x

Answer 4

y = -3/4x - 2
6x + 8y = -5
Slope Intercept form of the equation for a straight line is y = mx + b where m is the slope and b is the y intercept.
First equation is already in that form.
In the second equation, solve for y in the equation of:
6x + 8y = - 5
Subtract 6x from both sides of this equation to get:
8y = -6x - 5
Divide both sides of this equation to get:
y = (-6x - 5)/8 which becomes:
y = (-6/8)*x - (5/8)
Slope of the first line is -(3/4)
Slope of the second line is -(6/8)
-(3/4) is the same as -(6/8) so the lines are parallel.
