Question

Identify the slope and y-intercept for each

Answer 1

Answer:

Graph attached of all the problems.

Problem 1- Slope is m=6 and y-intercept is c=20

Problem 2-Slope is m=2 and y-intercept is c=10

Problem 3-Slope is m=-3 and y-intercept is c=20

Problem 4-Slope is m=5 and y-intercept is c=10

Problem 5-Slope is m=3 and y-intercept is c=6

Step-by-step explanation:

Given : 5 problems

To identify : The slope and y-intercept for each problem and also show the graph.

Solution :

Slope intercept form is y=mx+c

where m is the slope and c is the y-intercept

Problems:

Problem 1 - John began his job making $20 the first day. After that he was paid $6.00 per hour.

Y = 6x + 20

Comparing with the slope - intercept form

Slope is m=6 and y-intercept is c=20

Graph is attached below (1)

Problem 2 -  A membership to Movie Night Movie Club costs $10 plus $2 per movie.

Y = 2x +10

Comparing with the slope - intercept form

Slope is m=2 and y-intercept is c=10

Graph is attached below (2)

Problem 3 - You start out with $20 and then spend money in a store where every item is $3.

Y = -3x + 20

Comparing with the slope - intercept form

Slope is m=-3 and y-intercept is c=20

Graph is attached below (3)

Problem 4-Your weight-lifting class cost you a $10 fee up front and $5 per class after.

Y = 5x + 10

Comparing with the slope - intercept form

Slope is m=5 and y-intercept is c=10

Graph is attached below (4)

Problem 5 -You join a paperback book club for $6, and then spend $3 per book.  

Y = 3x + 6

Comparing with the slope - intercept form

Slope is m=3 and y-intercept is c=6

Graph is attached below (5).

Answer 2

Y = 6x + 20
Slope: 6
Y - Intercept: 20

y = 2x + 10
Slope: 2
Y - Intercept: 10

y = -3x + 20
Slope: -3
Y - Intercept: 20

y = 5x + 10
Slope: 5
Y - Intercept: 10

y = 3x + 6
Slope: 3
Y - Intercept: 6
