Answer: -5/6
Step-by-step explanation:
1) You have to do rise over run (if you can not do rise over run then you must pick 2 points that you can easily identify).
2) OR pick 2 points
(-4,1) (2,-4)
x1 = -4
y1 = 1
x2 = 2
y2 = -4
Equation to plug into: m= y2 - y1 / x2 - x1
(m is slope)
m = -4 - 1 / 2 - - 4
m= -5 / 6

Answer:
x = 5.5
EF = 14
Step-by-step explanation:
We can use ratios to solve
AG 7
----------- = -----------------
EG 2x+3
We know that EG is 2 times AG since A is the midpoint
AG 7
----------- = -----------------
2 AG 2x+3
Canceling like terms
1 7
----------- = -----------------
2 2x+3
Using cross products
1 (2x+3) = 2*7
2x+3 = 14
Subtract 3 from each side
2x+3-3 = 14-3
2x =11
Divide by 2
x = 11/2
x = 5.5
EF = 2x+3 = 2*5.5+3 = 14
J is your answer.
Slope is rise over run + your Y intercept.
Your y- intercept is the point in the graph in which the line passes through, the line passes through -2, so you know -2 is going to be your answer at the end. And slope is rise/run.
From one point to another, you rise 1 time , and run over 3 so you know your answer is
y = 1/3x - 2
hope this helps :)
Call the output f(x)
Call the input x
f(x) = x - 3
