Input, x 4 8 12 16 20 output y 21 37 53 69 85 what is the equation

The equation is y = 4x + 5

Step-by-step explanation:

To find the equation to this table, pick two ordered pairs and use the slope formula to find the slope. For this we'll use (4, 21) and (8, 37).

m(slope) = (y2 - y1)/(x2 - x1)

m = (37 - 21)(8 - 4)

m = 16/4

m = 4

Now we can use that slope along with any point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - 21 = 4(x - 4)

y - 21 = 4x - 16

y = 4x + 5

the answer is c

hope this !

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
