I need help please take a look at this
Reika [66]

Answer:

y = x-1

-x+\dfrac32=-y\\\implies y=x-\dfrac32

The equations have the same slope but different y-intercepts. This means the lines are parallel and there is no solution (since they do not intersect).

I really need help with this question!
m_a_m_a [10]

Answer:

(s-6)/r

option D

Step-by-step explanation:

The slope-intercept form a line is y=mx+b where m is the slope and b is the y-intercept.

Compare y=mx+b and y=cx+6, we see that m=c and c is the slope.

Now we are also given that (r,s) is on our line which means s=c(r)+6.

We need to solve this for c to put c in terms of r and s as desired.

s=cr+6

Subtract 6 on both sides:

s-6=cr

Divide both sides by r:

(s-6)/r=c

The slope in terms of r and s is:

(s-6)/r.
