The equations will only have one solution because they have different slopes and also next time use desmos for those kinds of problems it’ll always help
For systems of equations try using graphing, substitution, and elimination. For example
{2x+7y=3}
{x=-4y}
You should first look at if you have a variable that can be substituted (using substitution) and in this case we do! you plug in the x into 2x meaning 2(-4y)+7y=3
1) distribute -8y+7y=3
2) combine like terms in this case -8y+7y= -1y
3) solve -1y=3
y=-3
so currently our solution is (0,-3)
now we solve for x.
we plug our solved variable (y) into 7y
7(-3) and our equation looks like this
2x+7(-3)=3
1) distribute 7(-3)=-21
2) rewrite then solve 2x+(-21)=3
3) isolate variable -21+21 & 3+21
4) 2x=24
5) solve 2/24 = 12
Meaning our solution is (12,-3)
This is how to solve by substitution.
Answer:
what class are you in? if you have a book you can use this site called slader it gives you every answer for free and there is steps. HOPE THIS HELPS.
Step-by-step explanation:
Answer: The answer is D.) -2 and I'm correct :)
Step-by-step explanation:(-3,0) and (-4,2)
M=y2-y1
x2-x1
M= 2-0= 2
-4-(-3) = -1 ^Both equal to -2
