<span>Substitute y = -5x - 17 into the first equation:
-3x - 3y = 3
-3x - 3*(-5x - 17) = 3

-3x + 15x + 51 = 3
-3x + 15x = 3 - 51
12x = -48
x =-48/12 = -4 

y = -5x - 17 = -5*(-4) - 17 = 20 - 17 = 3 

so the solution is x = -4, y = 3</span>

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
beks73 [17]

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)
