Answer: (A) y=-2x

Step-by-step explanation:

Lets plug in the point (2,-4) for each equation.

-4=-2(2) this is correct

-4=2*2

-4=4 This cannot be true

-4=-2+3 =-4=1 This is false

Lastly, -4=2-4 this is false because -4 can't equal to -2.

So, A is the answer

The cost to join a gym includes a one-time membership fee, plus a monthly fee. John joined the gym and paid $325 for 6 months.Ab
Anettt [7]
We need to construct the system of equations in order to solve that problem. Let's denote one-time membership fee with x and monthly fee with y. Then we can write that John paid x+6y=325 and Abigail paid x+9y=475. Solving the system of equations \left \{ {{x+6y=325} \atop {x+9y=475}} \right., we find that x=25 and y=50. The monthly fee is 50 dollars.

What is the equation of the graphed line in standard form? −2x+y=6 y = 2x + 6 12x+y=6 12x−y=−6 A line graphed on a Coordinate pl
malfutka [58]

Answer:

(0, 6), (2, 7)

y = mx + b

m = (7 - 6)/(2 - 0) = 1/2 = 0.5

b = 6

y = 1/2*x + 6

1/2*x - y = -6

So, answer D is correct. But m is the fraction 1/2 and not 12.
