Exploring Slope and Slope-Intercept Form

What does the Greek letter delta (Δ) represent in the context of slope?

• Sum

• Change

• Difference

• Product

Which formula is used to calculate the slope between two points?

• (y2 - y1) / (x2 - x1)

• (x2 - x1) / (y2 - y1)

• (y1 - y2) / (x1 - x2)

• (x1 - x2) / (y1 - y2)

How can you identify a positive slope on a graph?

• The line goes down from left to right

• The line is vertical

• The line goes up from left to right

• The line is horizontal

What is the slope of a line that goes up 2 units and right 5 units?

• 5/2

• 2

• 1/2

• 2/5

What is the slope-intercept form of a linear equation?

• x = b + my

• x = my + b

• y = b + mx

• y = mx + b

In the slope-intercept form y = mx + b, what does 'b' represent?

• Origin

• X-intercept

• Y-intercept

• Slope

If a line has a slope of -3 and a y-intercept of 4, what is its equation?

• y = -3x - 4

• y = 3x - 4

• y = 3x + 4

• y = -3x + 4

What mistake is commonly made when calculating slope?

• Using the wrong formula

• Switching the rise and run

• Forgetting to subtract

• Multiplying instead of dividing

How do you find the y-intercept from a graph?

• Find the midpoint of the line

• Look for where the line crosses the y-axis

• Calculate the average of all points

• Look for where the line crosses the x-axis

What is the slope of a line that goes down 3 units and right 1 unit?

• -3

• 3

• -1/3

• 1/3
