Slope Intercept Form: Video Notes

What does the y-intercept represent in a graph?

• The point where the line crosses the y-axis

• The point where the line crosses the x-axis

• The slope of the line

• The maximum value of y

What is the formula for slope-intercept form?

• y = mx + c

• y = mx + b

• x = my + b

• ax + by = c

What does the 'm' in the slope-intercept formula represent?

• Maximum value of y

• Slope

• X-intercept

• Y-intercept

If a line's equation is y = mx + b, how can you identify the y-intercept?

• It's the value added to mx

• It's the product of m and x

• It's the value of m

• It's the coefficient of x

In the context of slope-intercept form, what does 'b' represent?

• The slope of the line

• The y-intercept

• The maximum value of x

• The x-intercept

In the equation y = -4x + 8, what is the slope?

• -4

• 0

• 4

In the equation y = 1/3x - 9, what is the y-intercept?

• 0

• 9

• 1/3

What is the slope in the equation y = -3.75x?

• -0.75

• 3.75

• -3.75

What is the y-intercept in the equation y = 1/3x - 9?

• 1/3

• 0

• -9

• 9

How do you find the slope from a graph?

• Divide the change in y by the change in x

• Multiply the change in y by the change in x

• Add the change in y to the change in x

• Subtract the change in y from the change in x
