(3,-5) (-1,5) you have to find the slope
nirvana33 [79]

Answer:

Hope this helps!

Step-by-step explanation:

Slope = 5/-2

Slope (m) =

ΔY

ΔX

=

5

-2

= -2.5

θ =

arctan( ΔY ) + 180°

ΔX

= 111.80140948635°

ΔX = -1 – 3 = -4

ΔY = 5 – -5 = 10

Distance (d) = √ΔX2 + ΔY2 = √116 = 10.770329614269

Equation of the line:

y = -2.5x + 2.5

or

y =  

- 5 x

2

+  5

2

When x=0, y = 2.5

When y=0, x = 1

What is the y-intercept -x 3y=9?
dedylja [7]
(0, 3)

<span>-x + 3y=9
to figure out the y-intercept, you must put the equation into y-intercept form first: y = mx + b

</span><span>-x+3y=9
3y = x + 9
y = (x/3) + (9/3)
y = x/3 + 3

1+4=5 2+5=12 3+6=21 8+11=?
ziro4ka [17]
Okay so we just need to find out the pattern...
in this case the pattern is adding..
we did 
1 + 4 = 5 
2 + 5 = 12
we figure this one out by adding 2 and 5 twice so it look like this 
2 + 5 + 5 = 12 
now moving on to our next one 
3 + 6 = 21 
so we added 3 and added 6, three times so look
3 + 6 + 6 + 6 = 21 
so now 
8 + 11 = 96 because we added 8 and added 11, eight times look..
8 + 11 + 11 + 11 + 11 + 11 + 11 + 11 + 11 = 96 
so our answer to 8 + 11 is 96!
hope this helps:)
