An equation for annealing soda-lime glass is y (t) = -14t+500, where t is time in minutes and y is the temperature of the glass in ˚C.

What is the y-intercept of the function?

An equation for annealing soda-lime glass is y (t) = -14t+500, where t is time in minutes and y is the temperature of the glass in ˚C.

To find the y intercept, we plug in 0 for t

y intercept is the value, where time is 0 minutes

so we plug in 0 for t and find out y (0)

y (t) = -14t+500

y (0) = -14 (0) + 500 = 500

When t=0, the value of y = 500

So, y intercept is (0,500)
