What’s the awnser(can someone do these for me i’m begging you my parents are gonna kill me)

-3/2

(2x-14)/3

(-2,-6)

Step-by-step explanation:

I solved the first one for you already ( -3/2)

To make a line perpindicular to another line they need to intersect at a 90 degree angle. To do this the slope of the lines have to be the negative  reciprical (take the fraction, flip it, and apply a negative sign to it)

If you do this to -3/2 you get 2/3

If we follow our y=mx+b equation from before we (so far) have

2/3x+b=y

which means that we just need to solve for b

We also know that it crosses the point (7,0) which means that if we plug in 7 for x and 0 for y we can solve for b

we have

(2/3)*7+b=0

Solve for B

14/3+b=0

b= -14/3

Which means our equation looks like this

(2x-14)/3

our two equations look like this

(-3/2)x-9

(2x-14)/3

We need to find where their coordinates are the same (where they intersect)

We can do this by setting them equal to each other and then solving for x

we have

(-3/2)x-9=(2x-14)/3

solve for x

-4.5x-27=2x-14

-13= 6.5x

x= -2

Now that we know what x equals we can plug this into any of our two beginning equations

(-3/2)*-2-9=y

3-9=y

-6=y

Which means our coordinates are (-2,-6)

if you have any questions let me know
