Respuesta :
y -8 = x - 4
y = x -4 + 8
y = x + 4
where y = f(x) ( y is a function of x meaning that y value is determined with the help of the value of x)
f(x) = x +4
y = x -4 + 8
y = x + 4
where y = f(x) ( y is a function of x meaning that y value is determined with the help of the value of x)
f(x) = x +4
Answer:
Option 1st is correct
[tex]f(x) = x+4[/tex]
Step-by-step explanation:
Given the point-slope equation:
[tex]y-8 = 1(x-4)[/tex]
Apply the distributive property: [tex]a\cdot (b+c) = a\cdot b+ a\cdot c[/tex]
⇒[tex]y-8 = x-4[/tex]
Add 8 to both sides we have;
[tex]y-8+8 = x-4+8[/tex]
Simplify:
[tex]y = x+4[/tex]
Use notation: y = f(x)
then;
[tex]f(x) = x+4[/tex]
Therefore, the linear function represents the line given by the point-slope equation y – 8 = (x – 4) is, [tex]f(x) = x+4[/tex]
