Hi!
Step-by-step explanation:
![SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}](https://tex.z-dn.net/?f=SLOPE%3D%5Cfrac%7BY_2-Y_1%7D%7BX_2-X_1%7D%3D%5Cfrac%7BRISE%7D%7BRUN%7D)
![\frac{1-4}{0-(-3)}=\frac{-3}{3}=-1](https://tex.z-dn.net/?f=%5Cfrac%7B1-4%7D%7B0-%28-3%29%7D%3D%5Cfrac%7B-3%7D%7B3%7D%3D-1)
<u><em>Slope is -1.</em></u>
<u><em>Final answer is -1.</em></u>
<u><em>*The answer must have a negative sign.*</em></u>
Hope this helps!
Thanks!
Have a nice day! :)

2x+3y=45
x+y=10
Take the bottom equation and solve for y
x+y=10
Subtract x from both sides
y=-x+10
Substitute into the top equation
2x+3(-x+10)=45
2x-3x+30=45
Subtract 30 from both sides + add like terms
-x=15
Divide both sides by -1
x=-15
Answer:
6 and 9
Step-by-step explanation:
set up an equation and solve for x
(x+3) * x = 54
easiest way to to try some numbers.
if you know your multiplication tables...
what two number multiplied together are 54
be sure the numbers you are thinking of meet the rules
is one 3 more than the other
do they multiply together to get 54
