x + y = 6 AND x - y = 2
What (4 ,2)

WHAT IS SLOPE?
What is THE STEEPNESS OF A LINEAR EQUATION, OR M IN Y=MX+B, OR RISE OVER RUN.
100
NAME THE SLOPE AND Y-INTERCEPT OF THE LINEAR EQUATION. y = 3 + 2x
What is 2 and 3
100
y + 5 = 10
What is -5 from both sides and y = 5
100
y = x - 7 and y = - 4x + 3
(2, -5)
200
3x + 4y = 5 AND 3x - 4y = -11
(-1, 2)
200
WHAT IS THE Y-INTERCEPT?
What is B, OR WHERE A LINEAR EQUATION CROSSES THE Y-AXIS
200
y = 1
What is 0 and 1
200
2y = 14x -10
What is divide by 2 on both sides
200
y = x + 4 and y = -x
(-2, 2)
300
x + 5y = 15 AND -x - 2y = 0
(-10, 5)
300
WHAT IS AN X-INTERCEPT?
What is WHERE A LINEAR EQUATION CROSSES THE X-AXIS
300
x = - 4
What is undefined and there is none
300
3y - 1 = 15x
What is +1 to both sides, then divide by 3
300
y = -4x + 1 and y = 5x - 8
What is (1, -3)
400
3x+2y = 24 AND -x + 2y = 16
(2, 9)
400
WHAT IS A SYSTEM OF LINEAR EQUATIONS?
What is TWO LINEAR EQUATIONS WITH THE SAME TWO VARIABLES
400
2.5y = 10 - 5x
What is -2 and 4
400
5 + 5y = x
What is -5 from both sides, then divide by 5.
400
y + x = 3 and 2y = 4x - 6
(0,-3)
500
2x + 5y = 4 AND 4x + 7y = 11
(4.5, -1)
500
WHAT IS A SOLUTION TO A SYSTEM OF LINEAR EQUATIONS LOOK LIKE?
What is AN ORDERED PAIR, (X, Y)
500
3y = 90x + 600
30 and 200
500
10x - 4x + 4 = 2y
Combine 10x and -4x to get 6x. Then, divide both sides by 2 to get y = 3x + 2
500
4y = 2x - 8 and y = -x + 5.5
