With number 4. i dont understand and show work pls

y =

Step-by-step explanation:

A line perpendicular to 2x = 1 - 3y has the same gradient (or slope). To find this we must isolate the y:

Move the -3y over to the other side making it a +3y:

3y + 2x = 1

Move the +2x over to the other side making it a -2x:

3y = -2x + 1

Divide everything by 3:

y =

So the gradient is

Now as the points are given, (9 , 4)

The equation of the line so far is:

y = mx + c

4 = (9) + c

4 = -6 + c

Move the -6 over making it a +6:

4 + 6 = c

c = 10

So that means the full equation is:

y =

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
