Linear Fun with Graphs

What is the slope of the line represented by the equation y = 3x + 2? A) 3 B) 2 C) 0 D) -3 (Why did the line break up with the curve? It found someone more straight!)

• A) 3

• A) 1

• B) 5

• C) -1

If the equation of a line is y = -4x + 5, what is the y-intercept? A) 5 B) -4 C) 0 D) 4 (Why did the graph go to therapy? It had too many ups and downs!)

• -5

• 1

• 3

• A) 5

Which of the following points lies on the line y = 2x - 1? A) (0, -1) B) (1, 1) C) (2, 3) D) All of the above (Why did the coordinate plane break up? It couldn't find common ground!)

• (2, 1)

• (0, 0)

• D) All of the above

• (1, 2)

What is the equation of a line with a slope of 1 passing through the point (2, 3)? A) y = x + 1 B) y = x + 2 C) y = x + 3 D) y = x + 4 (Why did the slope get kicked out of the party? It was too steep!)

• y = 2x + 3

• y = x - 1

• A) y = x + 1

• y = -x + 5

If a line has a slope of 0, what type of line is it? A) Vertical B) Horizontal C) Diagonal D) Curved (Why did the horizontal line get a promotion? It always stayed on the level!)

• F) Circular

• B) Horizontal

• G) Ascending

• E) Perpendicular

What is the slope of the line that passes through the points (1, 2) and (3, 6)? A) 2 B) 3 C) 4 D) 1 (Why did the slope always carry a ladder? To reach new heights!)

• A) 2

• 3.5

• 1.5

• 0

Which of the following equations represents a vertical line? A) x = 4 B) y = 4 C) y = 2x + 1 D) y = -x + 3 (Why did the vertical line get lost? It couldn't find its direction!)

• A) x = 4

• x + y = 5

• y = 3

• x = -2

What is the y-intercept of the line represented by the equation 2x + 3y = 6? A) 2 B) 3 C) 0 D) 1 (Why did the y-intercept always get invited to parties? It was the life of the graph!)

• -1

• 4

• 5

• 2

If a line has a slope of -2 and passes through the origin, what is its equation? A) y = -2x B) y = 2x C) y = -x D) y = x - 2 (Why did the negative slope get a job? It was great at bringing things down!)

• A) y = -2x

• y = 0.5x

• y = -x + 1

• y = 3x

What is the equation of a line that is parallel to y = 3x + 1 and passes through the point (0, 2)? A) y = 3x + 2 B) y = 3x - 2 C) y = -3x + 2 D) y = 3x + 1 (Why did the parallel lines never get along? They always had the same direction but never met!)

• y = 3x + 2

• y = -3x - 2

• y = 3x + 3

• y = 2x + 1
