A science experiment begins with a metal at -100° Celsius. The following function describes the temperature change per minute: f(x) = 89x - 100°. How will the graph of this function change if the metal is at 25° at the start of the experiment?

Question

anonymous · Answer

The starting point on a linear equation is the y intercept. So what is the starting point in your equation?

anonymous · Answer

I don't know if you're asking me if it gave me one or if I'm supposed to find it in the equation

anonymous · Answer

forgive me I'm pretty slow sometimes

anonymous · Answer

f(x) is the same as y in a linear equation. So in F(x)=89x-100 what would be the y or f(x) intercept.

anonymous · Answer

-100? I'm not completely sure, linear equations really confuse me

anonymous · Answer

-100 is incorrect. To find the f(x) intercept you make x in your equation = 0 and solve for f(x).....Thus f(x) = 89(0) -100. So what will f(x) equal.  Hint..you were close on your answer.

So when I do that, at first, I multiply it by 89
0-100
-100
I think
