Answer 1

Answer:

neither

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x - 9 ← is in slope- intercept form

with slope m = 2

y = $\frac{1}{2}$ x + 3 ← is in slope- intercept form

with slope m = $\frac{1}{2}$

2 ≠ $\frac{1}{2}$ , then lines are not parallel

2 × $\frac{1}{2}$ = 1 ≠ - 1, then lines are not perpendicular

Answer 2

Answer:

perpendicular

Step-by-step explanation:

First of all

We'll find the slope (m) of y=2x-7

if I put x=0 then, y= —7

And if I put x=—1 then, y= —9

so, m= {—7-(—9)} /{0-(—1)}

m= (—7+9) / (0+1) = 2

Now we'll find the slope (n) of y= 1/2x —1

If I put x=1 then, y=—1/2

And if I put x= —1 then, y= —3/2

So, n= {—1/2 —(—3/2)} / {1-(—1)}

n= (—1/2 +3/2 ) / (1+1)

n= 1/2

So, slope (m) of y= 2x-7 and slope (n) of y= 1/2x —1

m × n = 2 × 1/2 = 1
