Question

Write the slope intercept form of the equation of each line.

1. 11x + 8y = -64

2. 2x - y = 14

3. 14x + 5y = 40

4. 5x + 4y=-32

5. x+y=0

6. x + 4y = 20

Answer 1

Slope intercept form;

y = mx + b

y - independent variable

x = dependent

m - slope

b - y-intercept.

1.

11x + 8y = -64

-11x -11x

8y = -11x - 64

2.

2x - y = 14

-2x -2x

-y = -2x + 14

/-1 -1

y = 2x - 14

3.

14x + 5y = 40

-14x -14x

5y = -14x + 40

/5 /5

y = -14/5x + 8

4.

5x + 4y = -32

-5x -5x

4y = -5x - 32

/4 /4

y = -5/4x - 8

5.

x + y = 0

-x -x

y = -x to make it easier (y = -1x)

6.

x + 4y = 20

-x -x

4y = -x + 20

/4 /4

y = -1/4x + 5

Answer 2

1. y = -11/8x - 8

2. y = 2x - 14

3. y = -14/5x + 8

4. y = -5/4x - 8

5. y = -x

6. y = -1/4x + 5
