Systems of Equations, Slope, Slope-Intercept Form, Writing Equations of Lines

Solve the system of equations using the elimination method.

Enter your solution as a coordinate point with NO spaces.

-6x + 6y = 6

-6x + 3y = -12

The solution to this system of equations is:

• (4, 3)

• (3, 4)

• (-4, 3)

• No solution

Solve the system of equations using the elimination method. Enter your solution as a coordinate point with NO spaces. 3x + y = -14 -2x - y = -9

Solve the system of equations using the elimination method.

Enter your solution as a coordinate point with NO spaces.

-2x + y = 10

8x - 2y = -28

Write an equation in slope intercept form given

slope = 1/3

y-intercept: (0, 0)

• y = x

• y = 0x + 1/3

• y = 0

• y = 1/3x

Write an equation in slope-intercept form given the graph:

• y = 4/3x + 0

• y = -3/4x + 2

• y = -4/3x + 2

• y = 3/4x + 2

write an equation in point-slope form given:

slope = 2/3

point: (3, 5)

• y - 3 = 2/3 (x - 5)

• y + 5 = 2/3 (x + 3)

• y + 3 = 2/3 (x + 5)

• y - 5 = 2/3 (x - 3)

Write an equation in point-slope form given two points:

(0, 2) and (4, 10)

**use the second point in your equation**

• y + 4 = 2 (x + 10)

• y - 10 = 1/2 (x - 4)

• y - 10 = 2 (x - 4)

• y + 10 = -2 (x + 4)

Given the graph, write an equation in point-slope form. **use the right-most point in your equation**

• y = -1x + 3

• y + 1 = -3 (x - 4)

• y + 1 = 1 (x - 4)

• y + 1 = -1 (x - 4)
