Finding Slope and Y-Intercept: Key Concepts and Techniques

What is the formula for finding the slope between two points?

• x2 - x1 / y2 - y1

• y2 - y1 / x2 - x1

• x1 - x2 / y1 - y2

• y1 - y2 / x1 - x2

When given a graph, what is the easiest method to find the slope?

• Using the distance formula

• Drawing a tangent line

• Counting the rise over run

• Using a calculator

If a line goes up 5 units and right 6 units, what is the slope?

• 5/1

• 1/6

• 6/5

• 5/6

What does the y-intercept represent on a graph?

• The lowest point on the line

• The point where the line crosses the x-axis

• The highest point on the line

• The point where the line crosses the y-axis

If a line has a positive slope, how do you count the rise and run?

• Up and right

• Down and right

• Up and left

• Down and left

What is the slope of a line that rises 2 units and runs 5 units?
