The coordinates of P and Q are (2,6) and (4,5) respectively. Equation of a line RS is Y= 2X -3. Determine if the lines are paral
Travka [436]

Answer:

Perpendicular

Step-by-step explanation:

Given points P=(2,6) and Q=(4,5)

The line RS is y=2x-3.

Now we know that the line joining any two points (x1,y1) and (x2,y2) has slope m=\frac{y2-y1}{x2-x1}

Now the slope of the line PQ is

m1=\frac{5-6}{4-2}= -\frac{1}{2}

We know that  the slope of the line in the form y=mx+c is m

So the line RS has slope m2=2

Now two lines are parallel if m1=m2

And those two lines are perpendicular if m1*m2=-1

here m1= -\frac{1}{2}    and m2=2

clearly m1*m2=-1

Therefore the two given lines are perpendicular

This is because multiplying by 1/5 is like dividing each term by 5

10k + 15 = 5 • (2k + 3)
