FINDING SLOPE AND Y INTERCEPT FROM EQUATION WORKSHEET

Find slope and y intercept of the line given below.

Problem 1 :

x + 4y = 8

Solution

Problem 2 :

2x - 6y = -12

Solution

Problem 3 :

y = - 2

Solution

Problem 4 :     

5x - y = 3

Solution

Problem 5 :

-5x + 10y = 20

Solution

Problem 6 :

-x - y = 6

Solution

Problem 7 :

2.5x - 5y = - 15

Solution

Problem 8 :

x = - 5/2

Solution

Answer Key

1)  Slope (m) = -1/2 and y-intercept (b) = 2

2)  Slope (m) = 1/3 and y-intercept (b) = 2

3)  Slope (m) = 0 and y-intercept (b) = - 2

4)  Slope (m) = 5 and y-intercept (b) = - 3

5)  Slope (m) = 1/2 and y-intercept (b) = 2

6)  Slope (m) = - 1 and y-intercept (b) = - 6

7)  Slope (m) = 0.5 and y-intercept (b) = 3

8) no y-intercept and the slope is undefined.

Solve each for y, identify m and y – intercept and graph each.

Problem 1 :

2y = 4x - 8

Solution

Problem 2 :

2x - y = -8

Solution

Problem 3 :

-4x + 3y = -9

Solution

Problem 4 :

6 - 2y = 5x

Solution

Problem 5 :

 5y = -15

Solution

Problem 6 :

-2x = 4

Solution

Answer Key

1)  2 is slope and y – intercept is -4.

2)  2 is slope and y – intercept = 8

3)  4/3 is slope and y – intercept = -3

4)  -5/2 is slope and y- intercept = -3

5)  slope is 0 and y- intercept is -3.

6)  slope is 2 and y- intercept is 4.
