Creating Equations from Graphs: Slope and Y-Intercept

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

• y = mx + b

• y = ax^2 + bx + c

• y = mx - b

• y = m + bx

In the equation y = mx + b, what does 'm' represent?

• Y-intercept

• Slope

• Constant term

• X-intercept

What is the y-intercept in the equation y = mx + b?

• The rate of change

• The point where the line crosses the x-axis

• The point where the line crosses the y-axis

• The slope of the line

How do you calculate the slope from a graph?

• Run over rise

• Rise over run

• Sum of x and y coordinates

• Difference of x and y coordinates

If you rise 2 units and run -1 unit, what is the slope?

• 1

• 2

• -1

• -2

What is the y-intercept if the graph crosses the y-axis at 2?

• 2

• -2

• 1

• 0

If the slope is 1/2 and the y-intercept is -4, what is the equation?

• y = 1/2x + 4

• y = 2x - 4

• y = 1/2x - 4

• y = -1/2x - 4

What is the slope if you rise 2 units and run 1 unit?

• -2

• 1

• 1/2

• 2

If the slope is 2 and the y-intercept is 3, what is the equation?

• y = -2x + 3

• y = 2x + 3

• y = 3x + 2

• y = 2x - 3

What is the simplified form of y = 1x - 6?

• y = -x - 6

• y = x + 6

• y = 1x + 6

• y = x - 6
