Question

y = 16x - 21

Enter the​ y-intercept(s). Select the correct choice below and fill in any answer boxes within your choice.

Answer 1

y = 16x -21 has y intercept = -21 ore l the point (0,-21)

when a linear equation is solved for y, the y intercept is the constant term

to find the x intercept set y=0

0=16x-21

16x = 21

x = 21/16 = 1 5/16 or 1.315 which is the point (21/16, 0)

the linear equation is graphically a straight line which has only 1 y intercept and only 1 x intercept

Or it's possible you meant y=16x^-21 if so,

then y=16/x^21

the y intercept is when x=0, but

y=16/0^21 = 16/0 which is undefined.

there is no y intercept. x=0 is an asymptote

same with the x intercept, which doesn't exist.

x^21= 16/y, the x intercept if any is when y=0

x^21= 16/(0) which is undefined

x = the 21st roof of 16/0 which is also undefined.
