Question

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.
y=-4x+3
-2x=8y=5
A. Parallel
B. Perpendicular
C. Neither

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.
y=-1/4x+10
-2x+8y=6
A. parallel
B. Perpendicular
C. Neither

Write y=(-5/8)x+3 in standard form using integers.
A. 5x+8y=-24
B. 5x+8y=24
C. 5x-8y=24
D.-5x+8y=24
PLEASE HELP!!!

Answer 3

express all lines in y = mx+ c format m gives the slope of the line
for 2 parallel lines slopes are equal ie. m1=m2
for perpendicular lines m1.m2 = -1

Answer 4

But that doesn't help me with the questions.

Answer 5

why ? showed you how to do such problems ... try yourself now.

Answer 6

I don't know how to do it!

Answer 7

first one is neither , second one is parallel , third answer : 5x+8y=24

Answer 8

can you help me with one last one?

Answer 9

y=(-5/8)x+3 so you need to remove the 8 from the denominator
you can do this by multiplying 8 on both sides of the equation
8y = 8(-5/8) x + 8x3
or 8y = -5x + 24
or 8y+5y = 24

Answer 10

No, I mean another one?

Answer 11

what is the prob ?

Answer 12

write the equation of a line that is perpendicular to the given line and that passes through the given points.
y-2=7/3(x=5); (-4,9)
A. y-9= -3/7(x-4)
B. y-9=3/7(x-4)
C. y-9=-3/7(x+4)
D. y-9=3/7(x+4)

Answer 13

y-2=7/3(x=5); check this part .. (x=5) should either be x+5 or x-5

Answer 14

I don't understand

Answer 15

an equality has two sides with one equal to sign in between
but your problem has y-2=7/3(x=5) two equal to signs ... which means the sum is incorrect

Answer 16

so it is none of the answers?

Answer 17

yes
