First, you would do y1-y2, which would be 6-4, which would be 2. Then you would do x1-x2, which would be 5-(-1), which equals 6. Then you would do 2/6, which equals 1/3. Then you would do (1/3)×-1, which would be -1/3. Then, 4-(-1/3), which would be 4 1/3. The equation is y=(1/3)x+4 1/3
Answer:
x = -1,5.4
Step-by-step explanation:
We have to solve equation f(x) = g(x) from graph.
In graph f(x) and g(x) will be equal at the point where they meet each other.
Other way to understand this is
since y will be value of f(x) and g(x) .
so we need same value of y for both f(x) and g(x)
and same value for y will be at point where both function meets each other.
now looking at graph ,
we can see that graph of function f(x) and g(x) intersect at two points
(-1,-10) and other is at (5.4,12)
Thus, value of x from pair of solutions (-1,-10) and (5.4,12) is x = -1, 5.4.
Let, the age of Kim = x
Then, Jordan's age = x + 7
It is given that, 4(x + 7) = 200
a) Equation would be: 4x + 28 = 200
b) Now, 4x = 200 - 28
x = 172/4
x = 43
So, Kim is 43 Years old.
c) Age of Jordan = x + 7
= 43 + 7 = 50
In short, Age of Jordan is 50 Years
Hope this helps!
I think it’s A because they only intersect once.
