Writing Slope Intercept Equations for Graphs

What is the general form of the slope-intercept equation?

• y = mx^2 + b

• y = ax^2 + bx + c

• y = mx + b

• y = a/x + b

Where does the Y-intercept occur on a graph?

• At the highest point of the line

• At the origin

• Where the line crosses the Y-axis

• Where the line crosses the X-axis

If a line crosses the Y-axis at 8, what is the Y-intercept?

• 1

• 8

• 0

• 7

How do you determine the slope of a line?

• By finding the Y-intercept

• By finding the X-intercept

• By calculating rise over run between two points

• By measuring the length of the line

If you move up 3 units and over 7 units to the right between two points on a line, what is the slope?

• 3

• 1/3

• 3/7

• 7/3

What does the slope represent in the context of a line on a graph?

• The point where the line crosses the X-axis

• The length of the line

• The steepness and direction of the line

• The point where the line crosses the Y-axis

What is the final equation of a line with a slope of 3/7 and a Y-intercept of 8?

• y = 3/7x + 8

• y = 3x + 8

• y = 8x + 3/7

• y = 7/3x + 8
