1.  y=-x

2. y=-3/2x-2

3. x=4

4. y=-2x-1

Step-by-step explanation:

slope intercept form is y=mx+b with mx being the slope and b being the y intercept

if its parallel it has to have the same slope.

perpendicular lines have the opposite slope and sign. so if its a whole number you put it over 1 and if its a fraction you switch the values in the numerator and denominator in addition to changing the sign. You keep the y intercept the same.

(2,0)(4,1)
slope = (1 - 0) / (4 - 2) = 1/2

y = mx + b
slope(m) = 1/2
use any of ur points(4,1)...x = 4 and y = 1
now sub and find b, the y int
1 = 1/2(4) + b
1 = 2 + b
1 - 2 = b
-1 = b

so ur equation is : y = 1/2x - 1 <==

So, the first thing we need to do is find the slope, so we'll put the equation into slope intercept form

y+17=2x\\y=2x-17

So, our slope in the original is 2, so to make it perpendicular we need to take the negative multiplicative inverse.  So, we flip the fraction, and multiply it by negative 1.  So, we get -1/2 for our new slope.  Now, we just put the numbers into point-slope form and solve


Y-1=-\frac{1}{2} (x+4)\\Y-1=-\frac{1}{2}x+2\\ Y=-\frac{1}{2}x + 3

C is the correct answer
