Systems by Elimination

What does the second equation need multiplied by so that the x's will eliminate?

• 2

• -1

• 4

• 0

• (3, 3)

• (1, 5)

• (1, 3)

• (7, -1)

• (-4, -2)

• (2, 5)

• (10, 2)

• (-8, -1)

Solve the system:

x + 6y = 17

-x + 3y = -8

• (5, 2)

• (11, 1)

• (1, 11)

• no solution

−4x − 4y = 0

4x + 4y = 0

• (−6, −4)

• Infinite number of solutions

• No Solution

• (6, 4)

• (0,0)

Solve using the elimination method.

• ( 1, -2)

• (1, 2)

• (-1, 0)

• (2, 1)

The Elimination Method requires equations be written in ____ form.

• Point Slope Form: y - y₁ = m(x - x₁)

• X = form

• Standard Form: ax + by = c

• Slope Intercept Form: y = mx + b

The solution of a system of linear equations is...

• the y-intercept (b)

• the intersection of the two equations on a graph

• the second equations' answers

• the slope (m)
