Can you give the things you have to match?
1) solve for x by multiplying each equation with the opposite number and making one a negative
-4(5x + 2y =-9)-4
5(4x +3y = 25)5
2) multiply on both sides of equal sign
-20x - 8y = 36
20x + 15y = 125
3) add all the like terms to get new equation
7y = 161
4) simplify
7y = 161
/7 /7
y = 23
5) make ordered pair and then input 23 into original equation
( x , 23)
5x + 2y = -9
5x + 2(23) = -9
5x + 46 = -9
-46 -46
5x = -55
/5 /5
x = -11
6) input to ordered pair
(-11, 23)
7) Thats your answer!
Answer:
A) y=-6x+1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-17-(-5))/(3-1)
m=(-17+5)/2
m=-12/2
m=-6
y-y1=m(x-x1)
y-(-5)=-6(x-1)
y+5=-6(x-1)
y=-6x+6-5
y=-6x+1
