You can put this solution on YOUR website! i have absolutely no idea what this means. can someone please help me with this question?: find the equation of the linear functions that has a slope of -3 and f(2)=6
:
Using the form y = mx + b
:
Slope is given as -3 so we have
y = -3x + b
:
f(2) = 6 means when x = 2, y = 6
:
In our equation, substitute 2 for x, and 6 for y to find b
-3(2) + b = 6
-6 + b = 6
b = 6 + 6
b = 12;
The equation is: y = -3x + 12
:
CAn be writtten: f(x) = -3x + 12
:
Check our reasoning:
You can see that: f(2) = -3(2) + 12 = 6
