If 5/4 is 400, then 1/4 is 80. 80*4 is 320. 320 is your answer. Pls make brainliest
You did not provide us with equations to select.
Find the slope m.
m = (1 - 2)/(3 - (-1))
m = -1/(3 + 1)
m = -1/4
Use the slope and one of the points and plug into the point-slope formula.
y - 1 = (-1/4)(x - 3)
Isolate y.
y - 1 = (-1/4)x + (3/4)
y = (-1/4)x + (3/4) + 1
y = (-1/4)x + (7/4)

Answer: 94x-1
Step-by-step explanation:
For this case, the first thing we must do is define variables.
We have then:
x: Maggie's age
y: Age of Maggie's brother
We write the system of equations that models the problem.
We have then:
We solve the system of equations.
For this, we use substitution:
From here, we clear the value of x:
Answer:
Maggie is 9 years old
If both (1,2) and (-3,-3) were reflected across the y-axis, the x coordinate would reverse. (1,2) would become (-1,2), and (-3,-3) would become (3,-3). In this case, the answer would be A.
