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)

Step-by-step explanation:
The question you should be asking yourself is, "80% of how many doctors is 240?" Algebraically, 80% is .8, "of" is multiplying, "how many doctors" is our unknown, and "is" means equals. Putting that all together:
.8x = 240 so
x = 300
