William is digging a hole to plant a tree. the hole has to be in 2 ft deep. he is able to dig at a rate of 1/2 ft. per minute. write an equation for when y, the amount he has left to dig is a function of x, the amount of time he has been digging

Step-by-step explanation:

Let

x = the amount of time William has been digging

y = the amount he has left to dig

The hole has to be in 2 ft deep. This means when William starts, the hole was 0 feet deep and has left 2 ft to dig. Hence, y-intercept is

He is able to dig at a rate of ft per minute. Thus, the slope is (negative because the depth left to dig is decreasing).

The slope-intercept form of the equation is so in your case this equation is

- 70

this is the answer for you hope it

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
