Two lines are perpendicular if and only if the product of their slopes is - 1.

So, you just need to find the slope of each line and find out the product of their slopes.

I will do one example for you.

L1: y = 3x + 5

L2: y = - 3x + 14

L3: y = -x/3 + 14

The slope of a line is the coefficient of the x.

So the slopes are:

L1: slope 3
L2: slope -3
L3: slope -1/3

So now multiply the slopes of each pair of lines:

L1 and L2: 3 * (-3) = - 9 => No, they are not perpendicular

L2 and L3: (-3) * (-1/3) = 1 => No, they are not perpendicular

L1 and L3: (3) *  (-1/3) = -1 => Yes, they are penpendicular.

Which answer is an equation in point-slope form for the given point and slope?
Naddika [18.5K]

Answer:

B (y-9)=5(x-1)

Step-by-step explanation:

Formula of straight line in Point slope form

(y-y_1)=m(x-x_1)

Here

m=5 \ and \ (x_1, y_1)=(1, 9)

therefore equation of line having slope 5 and passing through point )1, 9) is given as

(y-9)=5(x-1)

PLEASE HELP ASAP!!!
xeze [42]

Answer:

JM = 10

Step-by-step explanation:

Because MN║JL,

\frac{MK}{JM} = \frac{KN}{NL}

\frac{5}{2x + 4}  = \frac{6}{12}  =  \frac{1}{2}

2(5) = 1(2x + 4)

10 = 2x + 4

2x = 6

x = 3

JM = 2x + 4 = 2(3) + 4 = 6 + 4 = 10
