Question

The graph models the linear relationship between the water level of the river in feet and number of days the water level measured. Which function can be used to find y, the water level of the river after x days

Answer 1

Answer:

option 4, y=1/4x+16

Explanation:

to solve this you must find the slope and the y intercept.

slope is rise/run, and equal to 2/8 or 1/4

then, the find the y intercept, find where the line crosses the y axis. Here it is 16.

finally you plug these answers into the slope intercept form, y=mx+b. In this form, m= slope, x=days, and b= y intercept.

after you plug in your answers you are left with y=1/4x+16.
