PLZ HELP I DONT UNDERSTAND. Can someone explain this?
DENIUS [597]

Answer:

The equation for line m is;

5y = -3x + 36

The equation of line q is;

3y = 5x + 8

Step-by-step explanation:

Looking at the diagram, firstly, we can see that while n and m are perpendicular, q and m are parallel

We should also note that the the line m and q both share the point (2,6)

Let’s try and work to get the equation of the lines

For line n, we have two points (1,-1) and (4,4)

The slope here can be obtained by the equation;

m = y2-y1/x2-x1 = (4 -(-1))/(4-1) = 5/3

Now let’s get for equation m

When two lines are perpendicular, the product of their slopes is -1

Let’s say m1 is like n slope and m2 is like m slope

m1 * m2 = -1

5/3 * m2 = -1

m2 = -3/5

So the slope of line m is -3/5

To get the equation of line m, we use the point slope form

The point to consider is (2,6)

Hence;

y-y1 = m(x-x1)

y-6 = -3/5(x-2)

5(y-6) = -3(x-2)

5y -30 = -3x + 6

5y = -3x + 6 + 30

5y = -3x + 36

Since line n and q are also parallel, then their slopes are equal. Hence, the slope of line q is also 5/3

We use the point slope form to get the equation of line q

where m = 5/3 and point = (2,6)

Thus;

y-y1 = m(x-x1)

y-6 = 5/3(x-2)

3(y-6) = 5(x-2)

3y -18 = 5x -10

3y = 5x -10 + 18

3y = 5x + 8
