HELP ASAP!!!

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.
please help im rlly stressed this isnt multiple choiced btw bc someone thought it was

Answer 1

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
