PLS HELP I WILL GIVE BRAINLIEST TO CORRECT ANSWERWhat Is The Slope What Is The Yintercept What Does The Slope Of The Line Shown By The Points Mean In The Situat class=

Answer:

  1. The slope is 20 or 20/1
  2. The y-intercept is at (0,60)
  3. The slope of the line shows for every class, the cost of fees increases by $20 at the gym
  4. The y-intercept means that before a member can sign up for a class, they must pay a flat, one-time fee of $60

Step-by-step explanation:

  • the slope-intercept formula is y = mx + b
  • m = slope which is rise/run
    for the slope, there is a formula that uses any two coordinates that are on the graph
    y2-y1/x2-x1
  • b= y-intercept which is where the graph crosses the y-axis

Finding Slope:

  • the two coordinates that I will be choosing is (0,60) and (1,80)
  • using the slope formula stated above, I will plug in my coordinates. It does not matter which coordinate you choose as #1 and which one as #2, you just need to make sure that you keep it consistent
  • 80-60/1-0 = 20/1 = 20 is the slope

Finding Y-Intercept:

  • If you look at the graph, there is a point that is on the y-axis which is at (0,60). This means that the y-intercept is at (0,60)

Answer:

1.  Slope = 20

2.  y-intercept = 60

Step-by-step explanation:

The slope of the line is found by dividing the change in y by the change in x or "rise over run":

[tex]\implies \textsf{slope}\:(m)=\dfrac{\textsf{change in $y$}}{\textsf{change in $x$}}=\dfrac{80-60}{2-1}=\dfrac{20}{1}=20[/tex]

The slope of the line for the given situation is the fee per class. Therefore, there is a $20 fee for each class a customer at the gym attends.

-----------------------------------------------------------------------------------------------

The y-intercept is the y-value at the point at which the line intercepts the y-axis, so when x = 0.

From inspection of the given graph, y = 60 when x = 0.

[tex]\implies \textsf{$y$-intercept}=60[/tex]

The y-intercept of the line for the given situation is the membership fee for the gym.  Therefore, the membership fee for the gym is $60.
