The y-intercept is the starting point. Since the temperature started at -7, we know that b in y = mx + b has to be -7. m is the slope which in our case is 3 because the temperature is changing every hour. So, because the temperature is going up, it's +3. Our equation should be y = 3x - 7.

Masja [62]

We have

C is the cost

x is the units of a product at the factory

If

C= 35170

we need to find the value of x

The equation given is

C=43x+14100

so we have the value of C, so the equation if we substitute the value of C is

35170=43x+14100

we need to isolate the x

\begin{gathered} 35170-14100=43x \\ 21070=43x \\ x=\frac{21070}{43} \\ x=490 \end{gathered}

In that month,490 units can be produced for $35170.​
