a spring stretches in relation to the weight hanging from it according to the equation y = 0.75x + 0.25 where x is the weight in pounds and y is the length of the spring in inches.
a. graph the equation. including axis labels
b. interpret the slope and the y-intercept of the line.
c. how long will the spring be if a 2 pound weight is hung on it? will the length double if you double the weight? explain.
im rlly stressed this isnt multiple choiced btw bc someone thought it was

Step-by-step explanation:

A. I would suggest using desmos.com/calculator just put the equation and it will graph it for you. If you want to do it manually simply find x values like 1,2,3 and put it in the equation y=0.75x+0.25

The x-axis will be labeled as pounds and the y axis will labeled as length

B. the slope is 0.75 and the y-intercept is 0.25 because it's in the form of y=mx+b where m is the slope and b being the y-intercept

C. the spring will be 1.75 if there is 2 pounds on it because

y=0.75(2)+0.25

and if there is double that weight meaning 4 the length will be 3.25

y=0.75(4)+0.25

so no, it won't be double the length because in order for it to be double the length of 2 pounds it needs to be the length of 3.5

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
