Question

What is the slope intercept form of the function that contains the point (6,2) and has a slope of 3?

Answer 1

Using y = mx + C.  Slope = m,  m = 3.
y = 3x + c

Substituting the point (6,2) into  the equation,  x = 6, y = 2.
2 = 3(6) + c
2 = 18 + c
2-18 = c
-16 = c
c = -16.  Substituting into y = mx + c

Therefore  y = 3x - 16.

Answer 2

You can plug in the numbers like 2=3(6) + b then rearrange for b so 2-18=b so the answer to your question is y=3x-16
